Suitable for home or industrial on LPG natural gas coal gas monitoring devices. Excellent resistance to alcohol smoke interference.
1 using high-quality dual-panel design with power indicator and TTL signal output instructions;
2 with a DO switch signal (TTL) output and AO analog signal output;
3 TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
4 the analog output voltage the higher the concentration the higher the voltage.
5 for gas natural gas has better detection sensitivity.
6 there are four screw holes for easy positioning;
7 Product Dimensions: 32 (L) * 20 (W) * 22 (H)
8 with a long service life and reliable stability
9 rapid response and recovery characteristics
Input voltage: DC5V power (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output :0.1-0 .3 V (relatively clean) the highest concentration of voltage around 4V
Special note: The sensor is powered needs to warm up around 20S measured data becomes stable the sensor fever is a normal phenomenon because the internal heating wire if hot is not normal.
