NDIR CO2 Temperature and Humidity Sensor -

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 it’s a lot bigger and more expensive, but it is the real thing.

MH-Z16 NDIR CO2 Sensor with I2C/UART Interface Board | …

21/09/2015· The heating element inside a chemical CO2 sensor keeps the sensor warm so that the chemical reaction could happen and produce an continuous EMF as the output, which depends on the CO2 concentration. This NDIR measures the concentration of the CO2 by measure the received IR light strength, it only consume relatively high current during the ON state of the IR emitter. Also, the …

Building a CO₂ Monitor with Python on a Raspberry Pi | Nathan …

Very high levels of carbon dioxide can lead to such unpleasant effects as a racing heart, arrhythmia, blurred vision, and impaired consciousness. Very high levels, above 10% concentration (100,000 PPM) can cause convulsions, coma, and death. NASA engineers famously had to figure out how to adapt CO 2 scrubbers intended for the command module to function correctly on the lunar module to save the …
