MG811 / (CO2) CARBON DIOXIDE SENSOR BREAKOUT
Description
This sensor module has an MG-811 gas sensor on-board and circuitry to enable to work out of box. This MG811 sensor module is a little bit special because it require 6VDC to function properly. 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.
Features:
Comes with MG811 Carbon Dioxide CO2 gas sensor
Operating voltage must be 6VDC
Dual signal outputs: analog output, and TTL digital level output
On board LED is active low, when digital TTL output valid signal is low, the LED is activated.
Can be connected to microcontroller such as Arduino
Analog output: 0 to 2V
Size: 32mm x 22mm x 28mm (LxWxH)
Weight : 10g
