More Information
Bring weather science into the classroom with theΒ ELECFREAKS micro:bit Smart Climate Kit. Designed for use with micro:bitΒ V2, this practical STEM kit combines environmental sensors with the IoT expansion board, allowing students to build monitoring devices and investigate the world around them.

Measure wind speed, temperature, humidity, ultraviolet radiation and dust levels. Display readings on the included OLED screen or upload data to the cloud to record observations and explore changes over time.
Explore Weather & Environmental Science
Students can build a range of projects, including:
-
Smart weather station: Monitor environmental conditions and investigate weather patterns.
-
Temperature and humidity monitor: Compare readings in different locations or at different times.
-
Dust monitoring device: Explore changes in airborne dust levels.
-
UV monitoring device: Measure ultraviolet radiation and investigate how readings vary.
These projects help connect classroom learning with everyday observations, encouraging students to ask questions, gather evidence and interpret their results.
Connect Sensors to the Cloud
The IoT expansion board features an onboard Wi-Fi module, real-time clock and buzzer, along with connections for sensors and other components. Cloud connectivity introduces students to the Internet of Things (IoT) and shows how connected devices collect and share information.
The kit can be used with the ELECFREAKS Smart IoT educational platform to visualise sensor readings and explore environmental data.
Developed on IoT:bit Breakout Board

Coding & Classroom Learning
Supports Microsoft MakeCode, MicroBlocks and Python, giving students opportunities to explore both graphical and text-based programming. Online ELECFREAKS learning resources provide guidance for building projects and using the sensors.
Suitable for practical activities across STEM, Science, Geography and Computer Science, the kit supports learning in:
- Programming and electronics
- Weather and environmental monitoring
- Data collection and analysis
- Connected devices and IoT
- Problem-solving and project design
