DFRobot (SEN0133) Analog Hydrogen Gas Sensor, MQ8

Gravity analogue hydrogen gas sensor (MQ8) for Arduino has high sensitivity tohydrogen (H2) and less sensitivity to alcohol, LPG, cooking fumes. Hydrogen gasis highly flammable and will burn in air at a very wide range of concentrations.The sensitivity is able to be adjusted by the potentiometer. The output isproportional to the density of gas. Users can use analogue reading to read thedata from this sensor. To ease the difficulty of using this sensor, a gravityInterface is adapted to allow plugplay. The Arduino IO expansion shield is thebest match for this senor connecting to Arduino microcontroller.Specifications:- Accessory Type: ANALOGUE Hydrogen Gas Sensor (MQ8)- For Use With: Arduino Development Boards- Product Range: Gravity Series- 5V power supply, analogue interface type- Pin definition: 1-output, 2-GND, 3-VCC- Stable and long life- Size is 40 x 20mm (1.57" x 0.79")
