Description

This Grove-SHT4x digital sensor is based on Sensirion's industry-proven humidity and temperature sensors. It can provide constant temperature and humidity accuracy over an extensive measurement range, making it the best price/performance ratio available. And with the grove platform, you are ready to plug and play the SHT4x sensor on any microcontroller (Arduino) or microprocessor (Raspberry Pi).

The Grove-SHT4x digital 4th generation sensor comprises an entirely new and optimized CMOSens® chip, offering lower power consumption, a voltage supply 5/3.3 volts, and up to 32µA of idle current, which makes it highly suitable for low-power and battery-supported applications. It has an operating temperature range of -40°C to +125°C, an excellent 1.8% typical relative humidity accuracy from 25 to 75%, and a 0.2 °C typical accuracy from 0 to 75 °C.

The fully calibrated Grove-SHT4x sensor offers linearized digital output and NIST traceability. And our standard Grove four-pin I2C interface makes it easy to read or communicate with integrated circuits.

Due to the high accuracy of the SHT4x sensor and the compatibility of our grove system, Grove-SHT4x is perfect for high-end industrial applications, projects for hobbyists, learning projects for beginners, etc.
