SHT2x Digital Humidity & Temperature Sensors
The Sensirion SHT2x series of DFN digital humidity & temperature sensors are CMOSens® based. They are an industry standard, widely used humidity and temperature sensor. Humidity is measured using a capacitive sensor while temperature is measured using a band-gap sensor.<,BR/>,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. <,BR/>,SHT2x sensors are ideal for both high and low volume applications.<,BR/>,The SHT21P has a PWM output and the SHT21S has a PDM output, these can be converted into analogue outputs by the use of suitable low-pass filters.<,BR/>,<,B>,SHT20<,/B>, - Low cost, <,B>,SHT21<,/B>, - Standard, <,B>, SHT25<,/B>, - High Accuracy
