The SDS011 Air Quality Sensor experiment

The SDS 011 Sensor The SDS 011 Sensor is a quite recent Air Quality Sensor developed by Nova Fitness, a spinoff from the university of Jinan (in Shandong). With its size, it is probably one of the best sensor in terms of accuracy: While other sensors tend to focus on shrinking the sensor size, the SDS 011 has opted for a size tradeoff allowing it to use a larger fan.


Air Quality Sensor | MySensors Forum

20140803· Each MQ7 sensor will be different. The normal levels in a lab or home will be (should be!) well below the level that this sensor can detect and discriminate. It''s lower limit implied in the data sheet is around 50ppm, which is where it begins to be dangerous for continuous exposure. Do read wiki and other sources about carbon monoxide and levels that can occur under different conditions ...
