1. using high-quality dual-panel design, with power indicator and TTL signal output instructions;
2. with a DO switch signal (TTL) output and analog output AO;
3. TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
4. analog output voltage, the higher the concentration, the higher the voltage.
5. carbon monoxide detector has good sensitivity.
6. there are four screw holes for easy positioning;
7. Product dimensions: 32 (L) * 20 (W) * 22 (H)
8. With long life and reliable stability
9. Rapid response recovery characteristics
Input voltage: DC5V Power (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: about 0.1-0.3V (relatively clean), the highest concentration voltage 4V
