Detailed Description

Example for EXT4 extension board sensors and actuators - All editions.

Based on Matter multiple sensor example

The example shows how to create multiple sensor instances with the Arduino Matter API.

The example creates a Matter temperature and humidity sensor device and publishes data through them. The device has to be commissioned to a Matter hub first.

Compatible boards:

• Arduino Nano Matter
• SparkFun Thing Plus MGM240P
• xG24 Explorer Kit
• xG24 Dev Kit
