INTRODUCTION
"Greenhouse Effect" is melting the Earth ice
core every minute and creating dangerous icebergs. By knowing the exact
concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and
to protect our Earth. Here is the CO2 sensor designed by DFRobot lovely
engineer.
This is the first CO2 sensor in Arduino market. 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 which is
highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity
& temperature dependency.
·
Onboard heating circuit brings the
best temperature for sensor to function. Internal power boosting to 6V for
heating sensor best performance.
·
This sensor has an onboard
conditioning circuit for amplifying output signal.
To ease the difficulty of using this CO2 sensor,
a Gravity Interface is adapted to
allow plug&play. The Arduino IO expansion shield is the best
match for this CO2 senor connecting to your Arduino microcontroller.
This is an electrochemical CO2 sensor, it is suitable for
qualitative analysis. There are the other Infrared CO2 sensors, which could
make a quantitative analysis.
Gravity: Analog Infrared CO2 Sensor
For Arduino (0~5000 ppm), high precision, apply to Arduino and other
microcontrollers with ADC function.
Gravity: UART Infrared CO2 Sensor
(0-50000ppm), wide range, apply to Arduino, Raspberry
Pi and other microcontrollers with UART function.
