Dec 14, 2014· More Pictures and Circuit Diagram. Arduino Test Code for Two DS18B20 Temperature Sensors. Reading the CO2 Sensor. Components needed: 1x GC0017 CO2 Sensor. For CO2 sensing I decided to employ an NDIR based sensor from (GC0017, 020%). There are only 4pins we care about on the sensor (GND, , Rx, Tx) and its very easy to ...
Jan 06, 2021· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) 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 ...
I tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module. This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.
The circuit shown in Figure 1 is a complete thermopilebased gas sensor using the NDIR principle. This circuit is optimized for CO2 sensing, but can also accurately measure the concentration of a large number of gases by using thermopiles with different optical filters. The printed circuit board (PCB) is designed in an Arduino shield form ...
