See when water drops below a chosen point without putting a probe inside the container. A useful direction for a plant reservoir.
CAIBI’s proposed addition: Test one sensor on the actual container, add a clear stale-signal state and a mount. One sensor detects one threshold; it does not measure continuous volume.
Start with the original
Tutorial foundation
Tutorial read 10 October 2026. Keep as an unassessed bench experiment. Confirm sensor output voltage and ESP32 interface before wiring; wall material affects detection. The bare sensor is not established as waterproof. Pump control is outside this proposal.
See the original source for its photos and demonstrations. We have not copied imagery without confirmed reuse rights. A source prototype is not a photo of this proposed CAIBI build.

Check the source before buying
Review the source material I supply for Water reservoir low-level indicator. Make a table of what is provided, missing, contradictory or dependent on a paid service. Identify exact hardware revisions, firmware files, library versions, CAD files and licences. Separate creator claims from your proposed additions. Do not fill gaps with guessed specifications. Finish with one small test that can resolve the biggest uncertainty before I buy parts.

Plan the next step
I want to develop this idea: Water reservoir low-level indicator. Intended outcome: See when water drops below a chosen point without putting a probe inside the container. A useful direction for a plant reservoir. The source is https://circuitdigest.com/microcontroller-projects/contactless-water-level-monitoring-with-esp-now. CAIBI suggests: Test one sensor on the actual container, add a clear stale-signal state and a mount. One sensor detects one threshold; it does not measure continuous volume. First inspect the source I supply. Separate what it already does from proposed additions. Ask for my actual board, parts, skill level and missing files. Produce a small staged plan with one bench test per stage. Do not invent pin assignments, dimensions or completed test results.

Design a measured enclosure
Help me design a practical enclosure for Water reservoir low-level indicator. First ask for measured component dimensions, mounting holes, connectors, cable clearance, ventilation and operating conditions. Suggest a printable or off-the-shelf approach. Begin with a fit-test piece before a complete case. Label assumptions and do not invent an enclosure rating.

Check and document the result
Create a test log for Water reservoir low-level indicator. Intended outcome: See when water drops below a chosen point without putting a probe inside the container. A useful direction for a plant reservoir. Separate expected behaviour from observed results. Include power restart, disconnected inputs, communication failure and the actual physical use. Ask me to provide results, firmware versions, changes, photos and unresolved problems. Never mark a test passed without my evidence.
