Why LMP91051 cannot be used for Alphasense NDIR IRC-A1 ...

· I am working on to build my readout circuit for Alphasense NDIR IRC-A1 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.

CO2 Alphasense NDIR sensor (IRC-A1/AF) + ARDUINO UNO ...

· Hello experts, I am new to Arduino and would like to connect a CO2 Alphasense NDIR sensor (IRC-A1/AF) to one of the Arduino Analog Inputs (A0 to A5), powering everything with a 12VDC power source. The sensor has 4 pins, (+n/p-/GND/UTN). I am a little bit confused with wiring and schemes. Any advice on this? Thanks very much :)
