SGBotic has created a series of Micro:Bit EduFun Mini Project Kits with an aim of making advance devices available to micro:bit inventors. Much efforts have been devoted to designing the MakeCode block packages to remove the complexity of using these devices, making it easier for inventors to incorporate into their projects.
The AM2320 in this EduFun Mini-Project Kit is a low cost, easy to use digital temperature and humidity sensor. The sensor is designed to measure ambient temperature and relative humidity. It utilises I2C for communication, so only requires four wires to connect to your micro:bit board. The sensor is designed to refresh its reading every two seconds, so your sensor reading can be up to 2 seconds old.
The temperature accuracy of this sensor is probably in the range of 2 to 3 degree Celsius, and 5-10% for humidity.
A MakeCode block package has been developed to remove the complexity of using this sensor in your project.
The projects in the printed guide will guide through the wiring as well as using the MakeCode blocks to read the temperature and humidity, and print them on the LED matrix of the micro:bit board.

Take note that Micro:Bit, T-Expansion board and breadboard which are used in the project are not included in this kit. Instead of T-Expansion Board, you can also use any micro:bit breakout board that has SDA/SCL pin (pin 19 and 20). All of these can be purchased separately at sgbotic.com.
