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
