This article describes a circuit that 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.
· This is necessary because Alphasense has changed the device quite significantly between the first few firmware versions, as it is a new device. The pyopc library supports firmware versions 1417, with version 18 supported on the firmv18 branch which will be merged with master in the next few days.

I would really appreciate any help on this subject please! arduino raspberrypi hardware. Share. Follow asked Feb …
· I am working on to build my readout circuit for Alphasense NDIR IRCA1 CO2 sensor. I found one posting saying that. The thermopile output stage generates a voltage with a very low impedance (like a battery), while the Pyro detector output stage generates a voltage with high impedance so the LMP9105x is not well suited for pyroelectric detectors.
Alphasense Nitrogen Dioxide Sensors (NO2 Sensors) are available in a wide range of formats and both PPM and PPB variants, making them suitable for use in variety of applications, from fixed and portable detection instruments to environmental monitoring systems and networks.
