- Extended operating ranges: The sensor can operate between 0 and 100% RH and -40 and 125°C.
- Condensing environments: Fully functional in condensing or environment close to saturation. (with a variable power heater)
- Serial Protocol: Grove I2C interface with an ultra-low-power budget, standard, fast mode, and fast mode plus l2C address sensor.
- Stress-Test-Driven Qualification: SHT4x sensor is JEDEC JESD47 qualified.
Description
This Grove SHT40 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-SHT40 digital 4th generation sensor comprises an entirely new and optimized CMOSens® chip, offering lower power consumption, 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-SHT40 sensor offers linearized digital output and NIST traceability. And the standard Grove four-pin I2C interface makes it easy to read or communicate with integrated circuits.
Due to the high accuracy of the SHT40 sensor and the compatibility of Seeed Studio grove system, Grove-SHT40 is perfect for high-end industrial applications, projects for hobbyists, learning projects for beginners, etc.
Applications
- Climate Monitoring and Control
- Cold chain data loggers
- Smart Thermostats
- Anti-fogging
