Helping plants grow

Advanced | MakeCode | Computer systems, Design & technology, Networks

In the Tree protector project, students use the radio on the BBC micro:bit to create a prototype sensor to send alerts when trees are being illegally cut down.

In the more advanced Auto-farmer project, students make moisture sensors and create a prototype of an automated farming system.
