Features:
- For home or factory gas leakage monitoring devices, suitable for carbon monoxide and other combustible gases and monitoring devices
- High-quality, dual-panel design, with power indicator and TTL signal output instructions;
- DO switching signal(TTL) output and AO analog signal output
- TTL output valid signal is low. (When the output low signal light is on, it can be directly connected microcontroller or relay module)
- Analog output voltage:the higher the concentration,the higher the voltage
- Have better sensitivity to carbon monoxide detector
- Four screw holes,easy positioning
- Product Dimensions: 32 (L) * 20 (W) * 22 (H)
- Long life and stability
- Quick response and resume
- Electrical performance:
- Input voltage: DC5V
- Power (current): 150mA
- DO output: TTL digital 0 and 1 (0.1 and 5V)
- AO Output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V
- Special note: When the sensor is powered, it needs to be warmed up about 20S, so the measured data becomes stable, the heat sensor is a normal phenomenon, because its inside is with an electric wire, if not, unnomal.
