Esysense Motion Sensor Products — Complete Installation & Troubleshooting Guide (2026) | India

Author : Esysense Inspire Lighting | Published On : 16 Jun 2026

Quick Answer:

Installing Esysense motion sensor products: plug-and-play products (sensor bulbs, hinge lights, rechargeable lights) require no tools or electrician — replace the existing bulb and leave the wall switch permanently ON. Hardwired products (panel lights, tubelights, downlights, standalone sensors, staircase controllers) require standard mains electrical connection — a licensed electrician is recommended. For all products: never connect to a dimmer switch; always leave the wall switch permanently ON. This guide covers step-by-step installation for every product category and a 14-problem troubleshooting table.

 

Pre-Installation Checklist — All Products

 

• Power off: isolate the relevant circuit at the MCB before touching any wires. Verify with a non-contact voltage tester.

• Fitting compatibility: E27 (screw) or B22 (bayonet) for bulbs | surface ceiling with wiring for panels | existing T8 holder for tubes | false ceiling with 90-120mm depth for downlights.

• Switch type: motion sensor products require a standard ON/OFF switch left permanently ON. NOT compatible with dimmer switches, timer switches, or two-way switching.

• Wiring identification: Live (brown or red in India), Neutral (blue or black), Earth (green/yellow). Use a circuit tester if unsure.

• Product manual: every Esysense product includes a printed installation guide. Read model-specific wiring diagrams before proceeding.

 

Bottom line:

The most common installation mistake across all motion sensor products: leaving the wall switch in the OFF position (which kills power to the sensor) or connecting to a dimmer switch (which causes flickering or failure). The wall switch must be ON permanently.

 

Installing Motion Sensor Bulbs — 8 Steps (No Tools, 5 Minutes)

 

1. Switch the wall switch OFF.

2. Remove the old bulb — anticlockwise (E27) or push-and-rotate anticlockwise (B22).

3. Inspect the socket — clean if necessary, confirm center contact is not recessed or corroded.

4. Insert the Esysense sensor bulb — clockwise until snug (E27), or align pins, push, and rotate clockwise until it clicks (B22).

5. Switch wall switch ON — leave permanently ON from this point.

6. Allow 10-30 second startup calibration — brief flash or dim glow is normal during calibration.

7. Test: walk away from detection zone, wait 10 seconds, walk back in — bulb should illuminate within 0.5-1 second.

8. Day/Night test (LDR models): cover the sensor window with your hand in a lit room — bulb should illuminate. Remove hand — bulb should switch off after delay.

 

Installing Motion Sensor Panel Lights — 7 Steps (Licensed Electrician Recommended)

 

1. Isolate circuit at MCB. Verify power off with voltage tester.

2. Mark mounting position on ceiling. Drill and insert appropriate wall plugs for ceiling material.

3. Route mains cable to mounting position, leaving 200-250mm free for connection.

4. Connect: Mains Live (Brown/Red) to Panel 'L' terminal | Neutral (Blue/Black) to 'N' | Earth (Green/Yellow) to Earth symbol. Tighten all terminals firmly.

5. Mount panel to ceiling. Screws should hold the panel flat against ceiling with no gaps.

6. Restore power and test — walk into zone, panel illuminates. Leave zone, verify auto-off after delay.

7. Adjust sensitivity and delay potentiometers on the driver unit if needed (accessible from panel edge or rear).

 

Installing Motion Sensor Tubelights — T5 Ballast Bypass (Licensed Electrician Recommended)

 

The critical step is bypassing the existing ballast — the LED tube connects directly to mains AC, not through the ballast:

 

1. Isolate circuit at MCB. Remove the old fluorescent tube.

2. Disconnect the ballast from the end-cap wiring. For single-ended bypass (most common): connect Mains Live to one end-cap holder terminal, Mains Neutral to the other end-cap holder terminal. Consult the Esysense T5 wiring diagram for the specific model's bypass method.

3. Insert the LED motion sensor tube — align pins with end-caps and rotate 90 degrees to lock.

4. Restore power and test.

 

CRITICAL: Never install the LED motion sensor tube with the ballast still in circuit — this will cause immediate damage to the LED driver inside the tube.

 

Installing Standalone Sensors — Universal Wiring Principle

 

All standalone PIR, microwave, and photocell sensors wire in series with the controlled light's Live wire:

 

• Mains Live → Sensor 'L-IN' terminal

• Sensor 'L-OUT' terminal → Light fixture Live terminal

• Mains Neutral → Light fixture Neutral (direct, bypasses sensor)

• Mains Earth → Light fixture Earth (direct, bypasses sensor)

• Multiple lights: wire all lights' Live in parallel to sensor L-OUT — as long as combined wattage is within sensor load rating (typically 1000-2000W). One sensor controls all lights in a room simultaneously.

• Photocell: cut the Live wire of the outdoor light's supply cable and connect the two cut ends to photocell L-in and L-out. Mount sensor in weatherproof enclosure with sensor window facing open sky — not toward the light it controls.

 

Sensor Settings — Sensitivity, Delay, LDR

 

Sensitivity (SENS)

• Adjustment: Small potentiometer on sensor or driver

• Clockwise: Increases detection range

• Anticlockwise: Decreases range and reduces false triggers

• Recommended Starting Point: Middle position (50%) and adjust as needed

Time Delay (TIME)

• Adjustment: Potentiometer labelled TIME or DELAY

• Clockwise: Longer auto-off delay

• Anticlockwise: Shorter delay

• Recommended Starting Point: Middle position, then adjust according to the space

LDR Threshold (LUX)

• Adjustment: Potentiometer labelled LUX or LDR

• Clockwise: Activates at higher ambient light levels

• Anticlockwise: Activates only in near-darkness

• Recommended Starting Point: Indoor: Maximum clockwise | Outdoor: Middle position

 

Recommended Delay Settings by Space

 

• Corridor: 1–2 minutes

• Bathroom: 3–5 minutes

• Office Cabin: 10–15 minutes

• Meeting Room: 10 minutes

• Car Parking Bay: 3–5 minutes

• Storeroom: 2–3 minutes

• Staircase: 2–3 minutes

• Balcony: 2–3 minutes

 

Troubleshooting — 14 Common Problems and Solutions

 

Bulb or Panel Does Not Turn On

• Most Likely Cause: Wall switch OFF, MCB tripped, or wiring fault

• Solution: Ensure wall switch remains ON, check MCB, and verify wiring connections

Light Stays On Continuously

• Most Likely Cause: Continuous movement in detection zone, delay set to maximum, or nearby heat source

• Solution: Clear the detection area, reduce delay setting, and check for heaters or sunlight exposure

Light Switches Off While Occupied

• Most Likely Cause: Sensitivity too low, delay too short, or PIR performance affected by high temperature

• Solution: Increase sensitivity, increase delay, or upgrade to a radar sensor

False Triggers When Nobody Is Present

• Most Likely Cause: Ceiling fan airflow, direct sunlight, or nearby heat source

• Solution: Reposition sensor, reduce sensitivity, or use a radar sensor

Light Flickers

• Most Likely Cause: Dimmer switch in circuit, loose wiring, or incompatible LED load

• Solution: Use a standard on/off switch and check all electrical connections

Day/Night Bulb Activates During Daytime

• Most Likely Cause: LDR window blocked or facing a dark surface

• Solution: Reposition the sensor and adjust the LDR threshold anticlockwise

Day/Night Bulb Does Not Activate at Night

• Most Likely Cause: LDR threshold too high or nearby street lighting affecting the sensor

• Solution: Reduce the LDR threshold and shield the sensor from unwanted light

T5 Tube Flickers After Retrofit

• Most Likely Cause: Ballast not fully bypassed or incorrect wiring

• Solution: Verify ballast bypass wiring and check Live/Neutral connections

Staircase Lights Turn On Simultaneously

• Most Likely Cause: Sequential mode disabled or controller wiring error

• Solution: Enable sequential mode and verify channel wiring order

Cabinet Sensor Light Remains On When Door Is Closed

• Most Likely Cause: Sensor positioned too far from the door edge or sensitivity too low

• Solution: Move sensor closer to the door frame and adjust sensitivity

Hinge Light Battery Drains Quickly

• Most Likely Cause: Frequent door usage or poor battery quality

• Solution: Use fresh, quality batteries and ensure the light is not stuck ON

Voltage Protector Frequently Disconnects

• Most Likely Cause: Supply voltage outside configured limits

• Solution: Measure supply voltage and adjust thresholds to match local conditions

Sensor Panel Has Short Detection Range

• Most Likely Cause: Sensitivity set too low or sensor window obstructed

• Solution: Increase sensitivity and remove any obstructions

Multiple Sensor Bulbs Interfere with Each Other

• Most Likely Cause: Rare radar interaction

• Solution: Reduce sensitivity, test each bulb individually, and fine-tune settings if required. In practice, this is rarely a significant issue.

Frequently Asked Questions

 

Q: Do I need a licensed electrician to install Esysense products?

A: For plug-and-play products (sensor bulbs, hinge lights, foot lights, rechargeable lights) — no electrician needed, same as changing a standard bulb. For all hardwired products (panel lights, tubelights, downlights, standalone sensors, staircase controllers) — a licensed electrician is recommended for safe, standards-compliant installation per Indian Electricity Rules.

 

Q: Can I use two motion sensor bulbs in the same room?

A: Yes — each bulb operates independently. Radar sensor bulbs may have minor interactions but these rarely cause practical problems. For large rooms needing full coverage, two bulbs at either end of the room is the correct approach.

 

Q: My staircase LED strips are uneven in brightness — some steps dimmer than others. Why?

A: Voltage drop in the DC wiring — particularly on longer staircase installations. Use minimum 1.5 sq mm wire gauge for DC runs. For staircases over 10 steps, inject power at both the top and bottom of the strip run to equalize brightness along the full length.

 

Q: After T5 sensor tubelight installation, there is a brief 1-2 second flicker at startup. Is this normal?

A: Yes — a brief flicker during LED driver initialization at power-on is normal for some models. Continuous flickering during operation indicates an incomplete ballast bypass — recheck wiring against the product's wiring diagram.

 

People Also Ask

 

Q: How do I install a motion sensor bulb?

A: Turn off the wall switch, remove the old bulb, screw in the Esysense sensor bulb, then turn the wall switch back ON and leave it permanently ON. The motion sensor handles all switching from that point. No tools, no electrician, 5 minutes. Do not connect to a dimmer switch.

 

Q: Why does my motion sensor light keep switching off while I'm in the room?

A: Most common causes: delay is too short (increase via TIME potentiometer), sensitivity is too low (increase via SENS potentiometer), or a PIR sensor is losing sensitivity in high Indian ambient temperature. For summer-reliable performance, switch to an Esysense radar sensor model.

 

Q: What is the correct wiring for a standalone PIR motion sensor?

A: Mains Live → Sensor L-IN | Sensor L-OUT → Light fixture Live | Mains Neutral direct to light (bypasses sensor) | Earth direct to light. Multiple lights can be wired in parallel to the sensor L-OUT as long as combined wattage is within the sensor's rated load.

 

Conclusion

 

Correct installation is the foundation of reliable long-term performance from any Esysense smart lighting product. For plug-and-play products: 5 minutes, no tools.
