Product Overview

The SHT21P is a humidity and temperature sensor IC in 6 pin DFN package. It has become an industry standard in terms of form factor and intelligence. This device is reflow solderable with 3mm x 3mm foot print and 1.1mm height. It provides calibrated, linearized sensor signals in analogue PWM format. The SHT21P contains capacitive type humidity sensor, band gap temperature sensor and specialized analogue and digital integrated circuit all on single CMOSens chip. This yields an unmatched sensor performance in terms of accuracy and stability as well as minimal power consumption. PWM signal runs on base frequency of 120Hz. Pulling SCL high or low allows for switching between humidity and temperature respectively. The PWM signal may be converted to an analogue ratiometric interface by adding low pass filter, the SHT21P sensor offers an outstanding performance.
