FAQs | Alphasense

For more information please contact Alphasense, ... When ordering please specify your CO2 range: 0 to 5000 ppm, 0 to 5%, 0 to 20% or 0 to 100% CO2. How do NDIR sensors work? Gas diffuses into the optical cavity. Light from the infrared source passes through the optical cavity where it interacts with the gas before impinging on the detector. Certain gases absorb infrared radiation at specfic wavelengths …

Connecting CO2 sensor using USB - Sensors - Arduino Forum

06/05/2021· The AlphaSense CO2 sensor is connected to a software serial port on the Uno using a FTDI TTL 232R 5V cable, the same one used for the mini. Using an oscilloscope I confirmed that a signal was being sent out but couldn’t find anything coming in. I double then triple checked the connections, still nothing. I’m pretty sure the port settings are correct since I first connected with Matlab then copied …
