SENSIRION SHT25 Digital Humidity & Temperature Sensor

Specifications

Product Introduction

The SHT25 is a high accuracy humidity and temperature sensor IC. It is fully calibrated, providing digital output through an I2C interface. The sensor is embedded in a reflow solderable Dual Flat No leads (DFN) package with a 3 x 3mm footprint and 1.1mm height. It offers calibrated, linearized sensor signals in digital, I2C format. The sensor contains a capacitive type humidity sensor, a band gap temperature sensor, and specialized analog and digital integrated circuits on a single CMOSens chip. Every sensor is individually calibrated and tested, with lot identification printed on the sensor and an electronic identification code stored on the chip. The resolution can be changed by command, and a checksum helps improve communication reliability.
