The SHT31 Temperature & Humidity sensor could be the finest and highest-accuracy humidity sensor you can find, as it can acquire the relative humidity at only ±2% error. On the other side, it also features excellent performance in terms of temperature measurement, you can use it in some extreme conditions, like -40 degrees or 125 degrees, and it still keeps an accuracy of ±0.3 degrees.

If you are looking for a temperature & humidity sensor that is accurate and also easy to use for your Arduino projects, the Grove - Temperature&Humidity Sensor (SHT31) must be one of your choices!

If you are familiar with our Grove system, you should be aware of how easy it is to get started with such a module that has a GROVE prefix. We design it as a Grove module so you don’t need any bread-boarding, meshing or soldering to make it work.

What is Grove?

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.

If your development board is a Seeeduino, simply connect it to the I2C port and download a few lines of code, then you are ready to roll!

Note: As the sensor is quite sensitive to environmental conditions, please DO NOT touch it with your fingers as you might damage it.

Get Started with Industrial Sensors

SenseCAP S210x series industrial sensors provide an out-of-box experience for environmental sensing. Please refer to the S2101 Wireless Temperature and Humidity Sensor with higher performance and robustness for air temperature and humidity detection.

Upgrade to Industrial Solutions

With the SenseCAP S2110 controller and S2100 data logger, you can easily turn the Grove into a LoRaWAN® sensor. Seeed not only helps you with prototyping but also offers you the possibility to expand your project with the SenseCAP series of robust industrial sensors.

The IP66 housing, Bluetooth configuration, compatibility with the global LoRaWAN® network, built-in 19 Ah battery, and powerful support from APP make the SenseCAP S210x the best choice for industrial applications. The series includes sensors for soil moisture, air temperature and humidity, light intensity, CO2, EC, and an 8-in-1 weather station. Try the latest SenseCAP S210x for your next successful industrial project.
