INTRODUCTION
Gas Sensor module with the gas sensor is useful for gas leakage detection in home and industry. It can detect H2, LPG, CH4, CO, Alcohol, Smoke, Propane and other flammable gases.
The sensor detects the concentrations of combustible gas in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas from 300 to 10,000 ppm, operates at temperatures between -20C to 50C and consumes less than 150 mA at 5 V (only sensor current consumption)
FEATURES
- Outputs both analog and digital values
- Onboard LED indicates if the module is connected properly
- Another onboard LED indicates when threshold values are touched (turns on)
- Great for DIY projects and Arduino beginners
- M3 Mounting holes to mount the module on your desk or project
