🌿 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.
