🌿 Measure soil moisture 

Do you take good enough care of your green friends? Don’t worry it’s not too late to start!

First we have to locate the micro:bit pins on the Wappsto:bit and attach our external sensor using jumper wires.

This is where you connect your external sensors ⬇️

Great, now that you have attached the sensor, a simple code will do the rest. Remember to enter the correct pin. The higher value you measure, the more moist the soil is.

  • How are you plants doing?
  • What can you see when you measure before and after watering?

We’re using this moisture sensor for our example.

⚠️ Don’t put your sensor too deep in the soil, only use the part intended to get wet.
