ESP32 Arduino: Temperature, humidity and CO2 concentration ...

2018-06-11· As CO2 sensor, we will use an Analog Infrared CO2 Sensor from DFRobot, which we have been covering in the previous tutorial. This sensor is based on the NDIR technology and you can consult its Wiki here. As detailed in the previous post, the sensor outputs an analog voltage that is proportional to the concentration of CO2 in the air, in the range of V to V. These voltages correspond to ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

2021-07-25· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

2021-05-05· Hi all, I am developing a CO2 sensor and regulator for an incubator. I am linking a schematic of my design and hoping if I can get some feedback if there are any potential dangers. Basically, the LED represents the sensor which can only handle between 6v to 12v. The two motors represents my regulator (solenoid) and a pump which share the same voltage source.
