Sensirion SHT4xF Humidity and Temperature Sensor (with Filter)

The Sensirion SHT4xF humidity and temperature sensor (with filter membrane) is based on optimized CMOSens technology to ensure high reliability and seamless integration. The Sensirion SHT4xF has a wide operating voltage range, a small size, and a sturdy case. The sensor is ideal for measuring under harsh conditions in industrial applications. The integrated PTFE film provides additional particle protection and supports sensor operation in harsh conditions.

The SHT4x-F is available in six sensor versions:

● SHT40-AD1F: Digital humidity and temperature sensor, RH typical ±1.8%/ Max ±3.5%, I2C 0x44

● SHT40-BD1F: Digital humidity and temperature sensor, RH typical ±1.8%/ Max ±3.5%, I2C 0x45

● SHT41-AD1F: Digital humidity and temperature sensor, RH typical ±1.8%/ Max ±2.5%, I2C 0x44

● SHT45-AD1F: Digital humidity and temperature sensor with ultra high accuracy ±1.0% RH/±0.1°C

● SHT40I-AD1F: Digital humidity and temperature sensor for industrial applications

● SHT40I-HD1F: Analog humidity and temperature sensor for industrial applications
