Datasheet SHT20
Humidity and Temperature Sensor IC ▪ Fully calibrated ▪ Digital output, I2C interface ▪ Low power consumption ▪ Excellent long-term stability ▪ DFN type package – reflow solderable
Product Summary
The SHT20 humidity and temperature sensor of Sensirion Every sensor is individually calibrated and tested. Lot has become an industry standard in terms of form factor identification is printed on the sensor and an electronic and intelligence: Embedded in a reflow solderable Dual identification code is stored on the chip – which can be Flat No leads (DFN) package of 3 x 3mm footprint and read out by command. Furthermore, the resolution of 1.1mm height it provides calibrated, linearized sensor SHT2can be changed by command (8/12bit up to 12/14bit signals in digital, I2C format. for RH/T) and a checksum helps to improve communication reliability. The SHT2x sensors contain a capacitive type humidity sensor, a band gap temperature sensor and specialized With this set of features and the proven reliability and analog and digital integrated circuit – all on a single long-term stability, the SHT2x sensors offer an CMOSens® chip. This yields in an unmatched sensor outstanding performance-to-price ratio. For testing SHT2x performance in terms of accuracy and stability as well as two evaluation kits EK-H4 and EK-H5 are available. minimal power consumption.
