What is Crowbits-Air Quality Sensor?

The air quality sensor is used to check air quality.



How does it work?

The MP503 air quality sensor uses a multi-layer thick film manufacturing process. The heater and metal oxide semiconductors are fabricated on both sides of the micro AL2O3 ceramic substrate, encapsulated in a metal shell. When there is detected gas in the ambient air, the conductivity of the sensor changes. The higher the depth of the gas, the higher the conductivity of the sensor will be. Then, the value of the conductivity will be converted into the corresponding voltage value, which will be amplified by the amplifier and sent to the MCU for acquisition and conversion, and finally the current percentage of air quality will be obtained.



How to use it?

Connect the module to the A0 port and load the corresponding library file. Open the AirQuality_Sensor program and download it to the UNO main board. Open the serial debugging window and use the smoke test to see Low Pollution and other results.
