Gas sensor MQ-5 module (OT2018-D55)

Sensor for measuring the concentration of benzene, alcohol and smoke in the air, for example to detect gas leaks (gas alarm) or to measure the air quality. The threshold value from which the module reacts can be adjusted via a potentiometer.Please note that the sensor heats up and is used warm. Exact measurement results are only provided when the sensor is warm.Technical data• Gas concentration measuring range: approx. 10 - 10,000 ppm• Input voltage (VCC): 5 V• GND: earth connection• AOUT: Analog output (0.1 - 4 V)• DOUT: digital output (1/0 0.1V/5V)Attention: The sensor becomes warm during use!DimensionsLength: 3.5cmWidth: 2cmHeight: 2.2cm
