What is it?
A DIY kit that uses an extremely simple circuit and all of the components and materials you need to make your own solar powered Thirsty Plant detector. This is an easy and fun way to actually make your own sensor, connect it to the sun using a solar panel and learn something about the hunger of your plants. Enter the world of creative technology by doing something both fun and practical!
How does it work?
The Thirsty Plant detector takes about 1 hour to make – and includes plaster casting, circuit building, your own creative license and NO soldering at all! The sensor itself is inspired by the super clever chap over at the site: cheapvegetablegardener.com. It is a simple plaster cast with nails for electrodes and wire to connect to the Thirsty Plant circuit. When the sensor is in your plant’s soil, the resistance between the two nails in the sensor increases depending on how dry the soil is. If its completely dry, the resistance becomes infinite! (in other words, its as if there is nothing connecting the two nails). When this happens, the LED in the circuit turns ON – alerting you to the needs of your poor plant.
