Purecrea MQ-135 Gas Sensor Air Quality

With this sensor module, you can easily measure the overall air quality. The sensor features a digital output that activates once the trigger threshold is reached. The trigger threshold is set using the potentiometer on the module. The current sensor value is output via the analog output AO and can be read directly on a microprocessor, such as an Arduino Uno.
