Environment Science Expansion Board V2.0 - module with environmental sensors for micro:bit

Description

Expansion module with environmental sensors designed for micro:bit. The PCB has an integrated sensor for UV, temperature, humidity, air pressure, sound, light, water temperature and water quality TDS (Total Dissolved Solids), soil moisture sensor, TVOC and a CO2 sensor.

The board was designed with STEAM education in mind. It enables students to measure environmental parameters useful for scientific experiments with an extensive array of sensors. This helps them to explore and understand the natural phenomena found in their everyday environment. The kit aims to provide students with a platform for learning science theory combined with hands-on exercises.
