Overview: Datasheet SHT21
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 SHT21 humidity and temperature sensor of Sensirion has bee an industry standard in terms of form factor and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1.1 mm height it provides calibrated, linearized sensor signals in digital, I2C format.
The SHT2x sensors contain a capacitive type humidity sensor, a band gap temperature sensor and specialized analog and digital integrated circuit – all on a single CMOSens® chip. This yields in an unmatched sensor performance in terms of accuracy and stability as well as minimal power consumption. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out by mand. Furthermore, the resolution of SHT2x can be changed by mand (8/12 bit up to 12/14 bit for RH/T) and a checksum helps to improve munication reliability.
