Grove - Temperature & Humidity Sensor (SHT31)

Grove - Temperature and humidity sensor (SHT31)

Measures temperature and humidity with high accuracy ±2 % RH and ±0.3 °C respectively. Based on the Sensirion SHT3x-DIS sensor and offers exceptional intelligence, reliability and improved accuracy.

You can use the sensor in extreme conditions such as -40 degrees or 125 °C and still maintain an accuracy of ±0.3 degrees. It also has an alarm mode that allows you to monitor environmental conditions (humidity and temperature) relative to programmable limits.

Ideal for industrial automation, smart home systems, etc.

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. We offer different Grove Shields to connect to the Grove system with various microcontrollers.
