Grove - Temperature & Humidity Sensor (SHT31)
Sold outGrove - Temp&Humi Sensor(SHT31) is a highly reliable, accurate, quick response and integrated temperature & humidity sensor.
Overview
The sensor(chip) used in the module is designed with Sensirion’s CMOSens® technology. The chip is well calibrated, linearized and compensated for digital output.
The typical accuracy of this module can be ±2%RH (for relative humidity) and ±0.3°C (for temperature).
This module is compatible with 3.3 Volts and 5 Volts and hence does not require a voltage level shifter. This module communicates using with I2C serial bus and can work up to 1 MHz speed. We also have provided a highly abstracted library to make this product more easier to use.
Using the sensor is easy.
For Seeeduino (compliant with Arduino), just connect this breakout board with the main control board via Grove cable.
Then use the provided library and example/demo code available at GitHub to get your data. If you’re using an Arduino without a Base Shield, simply connect the VIN pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5) and SDA to I2C Data (Analog 4).
Features:
- Highly reliable, accurate and quick response time
- Grove compatible and easy to use
- Well calibrated, linearized, compensated for digital output
- Highly abstracted development library

Save the date on May 28th-30th, Arduino will be back at SPS Italia in Parma, showcasing how our open-source solutions are revolutionizing the industrial sector with high performance and accessibility. At Arduino’s booth #C020, hall 7, we’ll be presenting the latest additions to our ecosystem, designed to help companies of all sizes embrace digital transformation and the Industrial IoT. Here’s a sneak peek at what’s in store: Opta: the “Swiss Army knife” of industrial automation Opta is our versatile micro PLC: reliable, secure, and open-source, it avoids vendor lock-in and is the ideal choice for both newcomers and seasoned professionals. Opta can be programmed with standard IEC 61131-3 languages or within Arduino’s environment, offering unmatched flexibility. “With Opta, we aim to support companies looking for increased visibility into their processes through IoT retrofitting, breaking down barriers to industrial automation, and those that produce machinery, seeking a ready-to-use controller for IoT and edge AI. Opta offers high performance, secure connectivity, and unprecedented programming flexibility at an affordable price,” says Arduino’s CEO Fabio Violante. Opta Expansion Modules to boost your projects New expansion modules allow you to enhance Opta’s capabilities: the Arduino Pro Opta Ext D1608E, Arduino Pro Opta Ext D1608S, and Arduino Pro Opta Ext A0602 provide additional programmable inputs, relay outputs, and analog I/O options for diverse data acquisition and control needs. Live demos for a hands-on experience Explore live demonstrations of Opta and other key products from our Portenta and Nicla families. Discover how these solutions can be applied to industrial automation, remote monitoring, predictive maintenance, and more! A strategic partnership with Melchioni Electronics We’re excited to collaborate with Melchioni Electronics, enhancing our reach and support for Arduino’s innovative solutions.
