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

Weather forecast for 7 days and current (local) weather data displayer using the Arduino Opla IoT Kit

We’re excited to announce the launch of the Arduino Oplà Kit, the first open programmable IoT platform that allows you to add smart connectivity to the devices around your home or workplace and build custom IoT devices. The Oplà IoT Kit contains all the hardware necessary to create eight connected applications, access to an online platform with assembly instructions, and a 12-month subscription to the Arduino Create Maker Plan. This kit is perfect for beginners with basic DIY experience, while more advanced users can leverage it to customize and hack their smart applications and devices, with full control of their data and processes. Eight out-of-the-box projects to connect your home or workplace The projects included in the Oplà IoT Kit enable users to turn everyday appliances into smart appliances, which can be controlled remotely on a mobile phone: Remote Controlled Lights — Change color, light modes, and switch on/offPersonal Weather Station — Record and monitor local weather conditionsHome Security Alarm — Detect motion and trigger warningsSolar System Tracker — Retrieve data from planets and moons in the solar systemInventory Control — Track goods in and outSmart Garden — Monitor and manage the environment for your plantsThermostat Control — Smart control for heating and cooling systemsThinking About You — Send messages between the kit and the Arduino IoT Cloud Create, connect, control. The Internet of Things has never been so easy! No soldering is required with the Oplà IoT Kit, which is based on a MKR IoT carrier with an OLED color display, on-board environmental sensors, and capacitive touch buttons. The kit also includes a MKR WiFi 1010 board, a circular plastic enclosure and supporting accessories, such as two cables, a motion sensor, a moisture sensor, and a USB cable. To build applications, users can rely on the Oplà online platform. Each project includes goals, an intro to the components,
