MQ-4 MQ4 Gas Sensor Module Methane Natural Coal Co Methane Detector Module Arduino
MQ-4 methane CNG gas sensor module for measuring the concentration of methane / natural gases. e.g. to detect gas leaks. (Gas alarm) Is often operated with Arduino and Raspberry Pi boards. The threshold from which the module responds can be set using a potentiometer. Please note: The module is heated up and operated warm. Exact measurement results are only delivered when they are warm.
Measuring range gas concentration: approx. 200 – 10000ppm Input voltage (VCC): 5V GND: ground connection AOUT: Analog output (0.1 – 0.3V to max. 4V at maximum concentration) DOUT: digital output (1/0 0.1V / 5V) Chips: MQ-4, LM393
Scope of delivery: 1 x MQ-4 methane CNG gas sensor module
