Mark several safe test depths, energize only long enough to record stable readings, then power down, rinse, and dry the tracks. Study repeatability and corrosion risk; do not use this board as a permanent reservoir sensor.
Short-duration water-level experiment is one focused build from the ESP32 Plant Monitoring Learning Kit. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.
Mark several safe test depths, energize only long enough to record stable readings, then power down, rinse, and dry the tracks. Study repeatability and corrosion risk; do not use this board as a permanent reservoir sensor.
ESP32U, DIY-025 conductive water sensor, breadboard, jumper wires, user-supplied shallow non-metallic container and clean water
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
Every item is in the kit — nothing extra to buy.
All 7 parts in one box, with this project and 6 more to build from them.
One of each part. Packs (resistor assortment, jumper wires) already hold more than a single build needs. Backorder parts ship once they arrive — the kit above has every part boxed today. Delivery is AED 20, free on orders AED 150+.
