SHT40/41 Temperature Humidity Sensor Module

SHT40/41 Temperature Humidity Sensor with IIC Interface For Arduino

Description

SHT4x-SHT40/41 is a digital sensor platform for measuring relative humidity and temperature at differentaccuracy classes. The I2C interface provides several preconfigured I2C addresses and maintains an ultra-low power budget. The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments.The four-pin dual flat-no-leads package is suitable for surface mount technology (SMT) processing.

SHT40 is based on the newly upgraded CMOSens®chip, which has lower power consumption and higher accuracy. The supply voltage range is extended to 3.3V to 5.0V, making it ideal for mobile and battery powered applications.
