SUKRAGRAHA Smoke Detector Board Module MQ-2 for Arduino Genuino System
Product Description
SUKRAGRAHA Smoke Detector Board Module MQ-2 for Arduino Genuino System
- Used for Detecting Smoke, Flammable Gas (e.g. LPG, Methanol , Ethanol) by SnO2 Gas Sensitive Materials
- Dimension: 32 mm x 20 mm x 22mm
- Input Voltage: 5V DC
- Result: Digital DO: 0.1V / 5V [TTL Switch] with DO LED display; Analog AO: 0.1 to 0.3 V [ Higher Value Means Higher pollution ]
The Analog Smoke/LPG/CO Gas Sensor(MQ2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and an adjustable resistor on board. <br><br>The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke. <br><br>It could be used in gas leakage detecting equipments in family and industry. <br><br>The resistance of the sensitive component changes as the concentration of the target gas changes.
