• SHT2x Digital Humidity & Temperature Sensors. The Sensirion SHT2x series of DFN digital humidity & temperature sensors are CMOSens® based. They are an industry standard, widely ***d humidity and temperature sensor. Humidity is measured using a capacitive sensor while temperature is measured using a band-gap sensor. The SHT2x sensors also contain a version 4 silicon chip with an amplifier, A/D converter, OTP memory and a digital interface. They come in a plastic package which leaves the sensor area open, protecting the devices from external impact and providing long-term stability. SHT2x sensors are ideal for both high and low volume applications. The SHT21P has a PWM output and the SHT21S has a PDM output; these can be converted into analogue outputs by the *** of suitable low-pass filters. SHT20 - Low cost, SHT21 - Standard, SHT25 - High Accuracy. CMOSens® based technology Fully calibrated I²C serial interface (Not SHT21P/SHT21S) Digital output Low power consumption Long-term stability Supply voltage range: 2.1 to 3.6 V.
