Made by Renesas, the single-channel, non-dispersive infra-red module is called RRH47000 and has automatic baseline calibration for measurement from 0 to 5,000ppm. Also in there are temperature and ...

A good example of this are the DHT11, DHT22, and AM2302 temperature and hygrometer sensors. ... It was similar to the BMP180, another quite popular MEMS temperature and relative humidity sensor.

What you'll learn: Features of the new TI relative-humidity sensor family. The RH sensor's dual capability of measuring temperature. Applications for the HDC302x family.

If you want to measure humidity (and temperature, and maybe even barometric pressure) in a device that you’re building, have a look at this comprehensive test of seven different options. We&#… ...
