Solar Plant Kit



Make your own moisture sensor out of plaster of paris and nails. Twist together your circuit and power it all with a solar panel that will tell an LED to flash when your plants need watering.

– Good for ages 8 to 108!
– Suitable for beginners. Can be hacked by more advanced makers with an Arduino
– Great introduction to electronics


Before you attach your solar panel to your circuit, feel the suns power by placing the wires onto your tongue and enjoying the buzz!


How to make a simple circuit using basic electronics. No soldering required to keep your plants happy!


Use the principles learnt in this kit to make more sensors around your space as well as circuits that have a practical application to help simplify your life. Use an Arduino microcontroller to create automatic watering cans or plants that tweet when they’re thirsty – the world of sensors and gardening is your oyster!
