Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

27-06-2021 · 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…

MQ-135 Gas Sensor with Arduino Code and Circuit Diagram

01-02-2021 · But, in this project, we will only play a buzzer. We will also include one red and one green LED. Circuit Diagram for MQ-135 gas sensor. We are going to receive analog value from the sensor. We used the Arduino A5 pin. So we connected the A5 pin with the 4th pin in the sensor. The sensor GND and VCC goes to Arduino GND and 5volt.

Arduino CO2 Meter- Measure CO2 using Arduino | Circuit Digest

17-11-2020 · In this project, we are going to use an MQ-135 sensor with Arduino to measure the CO2 concentration. The measured CO2 concentration values will be displayed on the OLED module and last we will also compare the Arduino MQ-135 sensor readings with Infrared CO2 sensor readings. Apart from CO2, we have also measured the concentration of LPG, Smoke, and Ammonia gas using Arduino.
