Test and Calibrate DHT22 / AM2302 / RHT03 hygrometers

2017-03-24· Capacitance humidity sensors are generally regarded as being susceptible to long term drift. I have seen little evidence so far of slow systematic drift, however after about nine months of reasonably consistent behaviour one of my sensors suddenly changed behaviour by a very large margin. A second failed after about one year of use. Output values changed by more than 20% RH. Had this …

Using ecobee3 humidity sensor to trigger my humidifier ...

2017-12-28· Thanks for the replies. I don’t have a device connected to my furnace and while it sounds like a great idea @vseven it might be a little too complicated for me to setup. I was think more along the lines of using the standard zwave/zigbee outlet and using SmartThings to read the humidity sensor in the ecobee3 to trigger the outlet.

Caring for Your Relative Humidity Sensor

Flooring installers use RH sensors with in-situ probes to test the humidity conditions deep within concrete slabs per the ASTM F-2170 standard. This lets them determine whether or not a concrete slab is ready to be built over. Wood product manufacturers might use thermo-hygrometers to make sure that the RH conditions in their storage areas match those of the region where their wood products ...

How to Check and Calibrate a Humidity Sensor - LEKULE

To check the accuracy of a humidity sensor, we use the “saturated salt” method to produce the standards. Put simply, certain salts (, ionic compounds such as table salt or potassium chloride), when dissolved in an aqueous solution, produce an atmosphere of a known humidity (see reference PDF). These chemical properties are used to create micro-environments of known relative humidity ...
