Nest Protect Teardown -

The plastic sensor baffle couples to a pair of ultrasonic transducers presumably to avoid weird echos from inside the enclosure interfering with their operation. There's also a light pipe that focuses the ambient light from outside the unit directly onto the on-board light sensor. This baffle also supports what I call the "Button Spider", a portion of the plastic that floats on thin plastic legs and allows you to push …

MH-Z19 Teardown | MySensors Forum

03/10/2017· So basically the CO2 molecules absorb specific IR light which results in a lower current of the photo diode. NDIR on Wikipedia. The sensor has no reference gas cell, so it needs factory calibration and probably a calibration after a couple of months of operation (Pull Hd pin to GND for 7seconds). The module has also a built in temperature sensor.
