Can be used as a gas leakage monitoring device for homes and factories, suitable for detecting liquefied gas, butane, propane, methane, smoke, etc;
Features:
1. Adopting high-quality dual panel design, with power indication and TTL signal output indication;
2. Has DO switch signal (TTL) output and AO analog signal output;
3. TTL outputs a valid signal at a low level. (When the signal light is on when the output is low, it can be directly connected to a microcontroller or relay module)
4. The output voltage of analog quantity increases with the concentration.
5. Has good sensitivity to liquefied gas, natural gas, urban gas, and smoke.
6. There are four screw holes for easy positioning;
7. Product dimensions: 32 (L) * 20 (W) * 22 (H)
8. Has long-term service life and reliable stability
9. Fast response and recovery characteristics

Note:
Special reminder: After the sensor is powered on, it needs to be preheated for about 20 seconds to stabilize the measured data. The heating of the sensor is a normal phenomenon because there is an electric heating wire inside. If it is hot, it is not normal.
