This is a simple-to-use gas sensor, suitable for sensing combustible gases concentrations in the air. Used for Detecting Smoke, Flammable Gas (e.g. LPG, Methanol , Ethanol) by SnO2 Gas Sensitive Materials. This sensor has a high sensitivity and fast response time. The module's output is either analog or TTL level. The module utilizes an MQ-2 sensor as the sensitive component and has a protection resistor and an adjustable resistor on board.
- Detectable Concentration: 300-10000ppm
- DO Output: 0.1-5V (TTL)
- Dual signal output (Analog output and TTL level output)
- Operating voltage: 5V
- Operating current: 150mA
- AO Output: 0.1-0.3V (Analog) [Higher values means higher concentration]
- Dimensions (approx.):30 x 19 x 20mm
