I2C digital humidity element boosts accuracy

EP&T Magazine   


SERVOFLO HYT271 digital humidity element is a capacitive polymer sensor has an I2C interface and uses an optimized thin film sensor connected to an ASIC, both on the same substrate. With a humidity measurement range from 0-100% rH, the device provides a low hysteresis of less than ?1% rH with an overall measurement accuracy of ?2.8% rH for the HYT271-S model. The linearity is less than 1% rH while the resolution is 0.02% rH. A temperature measurement is also included from -40 to +125C with an accuracy of 0.3C and resolution of 0.015C.
