MQ-9 MQ9 Carbon Monoxide CO Alarm Combustible Gas Sensor Module for Arduino

Description

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, unnormal.
