เซ็นเซอร์วัดก๊าซคาร์บอนไดออกไซด์ CO2 MG-811 Carbon Dioxide CO2 Sensor Module

เซ็นเซอร์วัดก๊าซคาร์บอนไดออกไซด์ CO2 MG-811 Carbon Dioxide CO2 Sensor Module 
About this product
This sensor module has an MG-811 on-board as the sensor component. There is an on-board signal conditioning circuit for amplifying output signal and an on-board heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.
