Hello friends, I hope you all are doing great. Today, I am going to share the new MQ Gas Sensor Library for Proteus V1.0 , with eight of the popular MQ sensors in one package: the MQ-3 (alcohol), MQ-4 (methane), MQ-5 and MQ-6 (LPG), MQ-7 (carbon monoxide), MQ-8 (hydrogen), MQ-9 (CO and flammable gases) and MQ-135 (air quality). They sit on the same small blue module with an analog output and a digital alarm, and now you can test your gas alarm, breathalyser or air-quality meter in Proteus before you solder anything. Behind the parts sits our own model , built on the curves of MQUnifiedsensor , the Arduino library most makers use with these sensors - so a sketch with that library reads back the gas you set . The heater warms up, the gas reaches the sensor with a delay, the trimmer sets the ...
