Taking a break

 We're taking a break and will be back soon. We will ship orders on 2017-07-03. 

By knowing the concentration of CO2 in the air, we can do something to reduce the Grenhouse Effect and protect our earth. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the  CO2 concentration is high enough (voltage is lower than threshold),  a digital signal (ON/OFF) will be released.

It has MG-811 sensor module onboard which is highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity and temperature dependency. All components have industrial quality which means stability and reproducibility.

An onboard heating circuit brings the best temperature for sensor to function. 5V power input will be boosted to 6V for heating. This sensor also has an onboard conditioning circuit for amplifying the output signal.

Notice: The new version of analog sensor port pin mapping has been changed as the following two features. {See Resources tab}
