Carbon Monoxide +LPG Gas Detector

Smart Home Gas Safety System

Silent danger ends here: Detect leaks, detect CO, and shut off gas supply automatically.

How it works

1. Continuous air monitoring
   This model is a wall-mounted and continuously monitors the surrounding air for both LPG (combustible gas) and CO.

2. Immediate alarm when danger levels are reached
   When gas concentration hits the preset thresholds (combustible gas: ~10% LEL; CO: ~100 ppm), the unit triggers an audible alarm (≥ 70dB) and visual alert.

3. Automatic gas shut-off
   Connected to a solenoid valve or relay output (optional) which interrupts the gas supply line instantly. While the official spec says “optional function … relay output NO or NC” you can configure it for automatic shut-off in LPG systems.

4. Resume and reset
   After the fault is cleared and the gas concentration drops, the sensor automatically resumes monitoring within ~30 s.

Dual detection: Combustible gas (such as LPG) and carbon monoxide (CO) (specification: combustible gas set-point at 10% LEL; CO at 100 ppm)

Detect it way before disaster strikes

Ideal Locations & Use Cases

Kitchens

Especially with LPG cylinders/tanks

Enclosed Utility Rooms

Bedrooms

If gas-powered dryers/heaters are used

Or boiler rooms using LPG or gas

Adjacent to gas-powered heaters or near gas lines

Installation:

Step-by-Step

Step 1

Select an ideal installation location

• For LPG detection: mount the unit within 0.3 m above the ground (as LPG is heavier than air)

• Avoid mounting near strong drafts, windows, or direct air vents.

• Maintain horizontal distance 2-4 m from cooker or gas source

Step 2

Power supply

• Connect to AC 120 V power supply

• Confirm the unit is powered and the display/LED is active.

Step 3

Install solenoid valve or relay if needed

• Mount solenoid valve on the gas line feeding the appliance (ideally near tank/regulator).

• Connect the relay output from the Detector to the solenoid valve wiring (NO/NC as required).

• Ensure arrow direction of valve aligns with gas flow direction.

Step 4

Testing & commissioning

• After full wiring, press TEST button or simulate low-level gas to ensure alarm triggers and valve shuts off.

• Verify normal conditions resume once test is cleared.
