MQ-135 Air Quality Sensor (MQ-135)
MQ-135 Air Quality Sensor - Analog and Digital Outputs
Tin Oxide (SnO2) sensor can detect air pollution gases such as ammonia, sulfide, benzene vapor etc.
Low digital output will indicate gas detection.
Analog output varies in proportion to amount of pollution.
+5V TTL operation.
Note: the sensor requires a minimum og 20sec. warm up time after power is applied.
