MQ-8 Hydrogen Gas Sensor Module MQ8 for Arduino

Description: The MQ-8 Hydrogen Gas Sensor Module can detect Hydrogen gas in the surrounding air. The concentration of the gas is output as an analogue voltage reading. This sensor can detect concentrations between 100-1000ppm and is suitable for portable gas detectors and home safety automation systems. The module requires two (2) different voltage inputs to operate. Heater voltage should be 5V (AC or DC) and Loop Voltage should be less than 24VDC. Specifications: Size: 32 mm X22mm X27mm Main chip: the LM393, MQ-8 gas sensor Working voltage: DC5V Gas Detected: Hydrogen Concentration Sensitivity: 100-1000ppm Voltage Inputs: Heater: 5V AC or DC, Tolerance: ±0.1V Loop Voltage: ≤24V DC Package Included: 1 X MQ-8 Hydrogen Gas Sensor Module MQ8 for Arduino
