nodemcu mg811
The NodeMCU MG811 is a gas sensor module based on the MG811 CO2 sensor. It is designed to measure the carbon dioxide (CO2) concentration in the air and output the data through a digital interface. The NodeMCU MG811 is compatible with the NodeMCU development board and can be programmed using the Arduino IDE. It is commonly used in indoor air quality monitoring systems and can detect CO2 concentrations ranging from 350 to 10,000 ppm. The sensor module also features a built-in temperature and humidity sensor to provide additional environmental data.
