Module Applications:
For home, carbon monoxide detection device environment. Suitable for carbon monoxide and gas detection.
Module Features:
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, the carbon monoxide detection with better 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
Electrical properties:
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.
