Measure CO2 Levels With Ardunio and K30 Sensor : 9 Steps ...

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won''t operate properly.

CO2 Sensor Arduino Compatible RobotShop

The CO2 Sensor Arduino Compatible is the first CO2 sensor in OSHW 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 MG811 sensor module onboard which ...

Infrared CO2 Sensor Module (Model: MHZ19B)

Do not use the sensor in the high dusty environment for long time. To ensure the normal work, the power supply must be among ~ DC rang, the power current must be not less than 150mA. Out of this range, it will result in the failure of the sensor. (The concentration output is low, or the sensor can not work normally.)

A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied. In other words, higher levels of CO2 correspond to larger numbers of people inside, and ...
