It raises easily at 4095 if you release some gas nearby. In order to calibrate this sensor, having a look at datasheet and at arduino library (MQUnifiedsensor) is very useful. What I understand from datasheet is when sensor is in fresh air (condition of calibration), the ratio Rair/Ro...
Sensor Support** The MQ Gas Sensor Carrier Board is a versatile tool for Arduino enthusiasts and professionals alike. It supports a wide range of gas sensors, including the MQ3, MQ2, MQ4, MQ5, MQ7, MQ9, MQ6, MQ8, and MQ135, making it a valuable addition to any sensor-based ...
