Grove - Temperature & Humidity Sensor (SHT31)
Grove - 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

We are excited to announce our team will be traveling to Amsterdam for The Things Conference on September 22nd-23rd, where Arduino will be among select exhibitors. The Things Conference is the world’s largest conference about LoRaWAN®, bringing together the industry’s major players contributing to this technology’s development in a two-day deep dive dedicated to making business operations smarter. This year’s edition will focus on the main topic of digital transformation – as seen through the lens of LoRaWAN®, of course! Connect with us at The Things Conference Don’t miss your chance to meet our experts in person at Amsterdam’s The Kromhouthal – a former marine engine factory now turned into a unique event venue. We’ll be showcasing some of our best LoRaWAN® products and solutions: The Portenta Vision Shield LoRa®, designed to boost Arduino Pro’s H7 module with the capability to run embedded computer vision applications, connect wirelessly via LoRa® to the Arduino Cloud (or third-party infrastructure), and activate systems upon the detection of sound events; The Portenta Max Carrier, which can augment Portenta H7 or X8 with LoRa® connectivity and transform existing Arduino Pro modules into single-board computers or reference designs that enable edge AI for high-performance industrial, building automation and robotics applications;The Arduino MKR WAN 1310, an entry-level option featuring the renowned versatility of the MKR family: a practical and cost-effective solution to add LoRa® connectivity to projects requiring low power;Last but not least, the newly launched WisGate Edge Lite 2 and WisGate Edge Pro: ready-to-use, industrial-grade gateways for LoRaWAN® connectivity powered by RAKwireless™. On September 22nd, the packed schedule of The Things Conference also includes a keynote by Sebastian Romero, Lead Interaction Designer & Creative Technologist at Arduino: “Predictive Maintenance with an Arduino-based
