MG811 Carbon Dioxide Sensor
MG-811 Carbon Dioxide Sensor Module (Carbon dioxide sensor) is a carbon dioxide sensor (CO2) sensor that is a Metal Oxide Sensor sensor, which must heat the tank to the specified level. (With the method of supplying power) will cause heat vapor and separate CO2 from the air. This sensor module has an MG-811 onboard as the sensor component. A signal output circuit for heating the sensor The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. The output voltage of the CO2 increases.
Useful for greenhouses and medical projects. Sends an analog signal that decreases as the concentration of CO2 increases. This module also includes a digital output pin with TTL output. The Potentiometer on board is used to set the Digital Output Setpoint. After setting the potentiometer threshold, once that threshold is reached, an LED on the sensor will illuminate and the digital pin will give a HIGH voltage signal.
Features:
- High Sensitivity to CO2: Detects even low concentrations of carbon dioxide.
- Analog Voltage Output: Provides a variable voltage output corresponding to CO2 levels.
- On-board Heating Circuit: Maintains optimal sensor temperature for accurate readings.
- Signal Conditioning Circuit: Amplifies the output signal for better accuracy.
- Rapid Response and Recovery Time: Quickly detects changes in CO2 levels.
- Operating Voltage: Typically operates at 6V.
Applications:
- Air Quality Control
- Ferment Process Control
- Room Temperature CO2 concentration Detection
- Controlling environment horticulture
- Process control
Pinout:
- VCC: 6V ( You can use a 4 AA battery holder for this ).
- AOUT: Analog Output (voltage decreases as CO2 Levels increase).
- DOUT: Digital Output that goes HIGH when the threshold is reached (set the threshold by turning the onboard potentiometer).
- GND: 0V.
