Temperature and Humidity Sensor

Humidity readings can be indicators of the rain-snow transition zone, a region where percipitation transitions from liquid to solid form. Humidity readings can also be used to determine the effects of in-air water content on WSN communcations.


The SHT1x by Sensiron features a version 4 Silicon sensor chip. Besides the humidity and temperature sensors, the chip contains an amplifier, A/D converter, OTP memory and a digital interface. While the sensor is made of a CMOS chip, the sensor housing consists of an LCP cap with epoxy glob top on an FR4 substrate. Electrical properties of various substrates on the sensors help infer humidity and temperature conditions.
