Soil Moisture Sensor Circuit Diagram. The circuit can be used to detect moisture in any substance like plants soil wood wall floor irrigation areas etc. We can use insulation removed copper wires as sensor here or you can use conducting material nail as a moisture detecting sensor.
In the previous circuits of moisture sensors like plant soil moisture tester circuit or moisture sensor alarm. This is very simple and interesting circuit for electronics lovers. As you can see the circuit diagram is really simple.
This soil moisture detector probe is homemade and built using general purpose pcb perf board.
Jan 24 2018 in this project we are going to build a transistor based simple soil moisture detector circuit. I2c 16 2 lcd 12vdc water pump and capacitive soil moisture sensor interfacing with arduino uno. This soil moisture detector circuit is very simple. As you can see the circuit diagram is really simple.
