Project overview
A moisture probe in the pot triggers a small pump from a reservoir whenever the soil dries past the set point. It is a simpler, self-contained cousin of the full irrigation project — no networking, no dashboard, everything visible on the model itself.
That simplicity is the point for school and early diploma work. There are four things to explain: the probe, the threshold, the relay and the pump. A student can own all four completely, which makes for a confident demonstration.
The reservoir has its own level indication so the system warns before it runs dry, and a maximum run-time limit prevents the pump emptying the whole reservoir into one pot if the probe comes loose.
Features
- Waters automatically when soil moisture drops below the set point
- Adjustable threshold with a documented calibration
- Reservoir level indication with a low-water warning
- Maximum pump run-time limit as a safety stop
- Compact enough to carry to school fully assembled
How it works
- 1The capacitive probe in the soil is read every few seconds.
- 2Readings are compared against the calibrated dry threshold.
- 3Below the threshold, the relay energises and the pump delivers water through the tubing.
- 4The pump stops when moisture recovers, or when the maximum run time is reached.
- 5The reservoir probe lights the low-water indicator when the supply needs refilling.
Components used
- Arduino Nano
- Capacitive soil moisture probe
- Mini submersible pump
- Water reservoir with level probe
- Relay module
- Potted plant and tubing
Questions about this project
How is this different from the smart irrigation project?
This one is entirely local and self-contained, suited to school and early diploma work. The smart irrigation system adds Wi-Fi, a dashboard and logging, which suits final-year submissions.
Will it overwater the plant?
No — the pump stops when moisture recovers, and a maximum run-time limit acts as a backstop if the probe is disturbed.
