Plant health sensor
Are your plants thirsty?
This sensor will show you the moisture level of 6 plants (and can even help you water them).
Get a deeper reading of the soil's moisture levels, and log it over time.
These sensors use the same technology as touchscreens, which makes them more rust resistant.
Check on 6 plants
You can connect between 1 and 6 soil sensors.
As an upgrade, you could even automatically water your plants.
An early prototype
Connected up to 6 sensors
Building the sensor
Connect the moisture sensor(s)
- Connect the soil sensor to pin A0. If you have more sensors, connect them to A1, A2 and A3 in similar fashion.
Plug in the RF-Nano Arduino
Plug the RF-Nano into its socket. The USB connector should be on the outside of the main board.
