New Products 8/11/21 feat. Adafruit SCD41 – NDIR CO2 ...

20210814· The SCD41 is a photoacoustic ‘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 it’s bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, air ...


What CO2 Sensor Range is Best for Your Application?

2 days ago· Carbon dioxide (CO 2) sensors and related monitoring devices are available in a diverse array of ranges, from 1000 ppm (parts per million) to CO 2. Choosing a sensor or monitor with an appropriate CO 2 measurement range is important, and this must be selected to meet the needs of the application in question. The narrower the range of CO 2 levels measured, the more accurate the …

It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm and two relays which can be triggered on a low CO2 (Generally above 1000 ppm) normally to switch on an extractor fan …


Indoor air quality sensor | Unipi

For models featuring a CO2 sensor, the LED indicates carbon dioxide concentration (green = low concentration, red = high concentration). For variants lacking the CO2 functionality, the LED then indicates air quality index roughly equivalent to CO2 concentration. In all models, the LED has a secondary function of indicating wireless communication and device status.


UltraLowPower CO2 Sensors Enable Wireless Remote ...

A wireless CO2 sensor suitable for use in IAQ systems consists of four major building blocks, a CO2 sensor, microcontroller, low power radio module, and a power source. Nondispersive infrared CO2 sensors work by illuminating the gas using a filtered incandescent light source and measuring the absorption using a light detector. However, the power consumed using this type of CO2 sensor is too ...
