ⓘ Some images are AI-generated illustrations, made to match this kit’s actual contents. Colours and small details may differ — see “In the box” and the kit details below for the exact parts.

Build a USB-powered ESP32 learning prototype that calibrates a capacitive soil sensor and a short-duration water sensor, reads a 3.3 V BME280, and reports local Serial Monitor data. The checked firmware includes guided calibration and fault handling; no pump, Wi-Fi dashboard, unattended control, or verified buzzer driver is included.

1. 1 Calibrated Plant-Monitoring Lab The kit's main build. Soil moisture, water level, temperature, humidity and air pressure stream to your computer every 2 seconds. You calibrate the t… Intermediate
2. 2 Soil-Moisture Calibration Study Discover why a soil sensor never gives a 'real' percentage. Record the raw reading in air and in water, then test dry, damp and wet soil, probe depth… Beginner
3. 3 Short-Duration Water-Level Experiment Lower the water sensor step by step into a container and watch the reading climb. The sketch learns the empty and full readings as you go, reports a… Beginner
4. 4 BME280 Room Environment Station One small chip, four readings: temperature, humidity, air pressure and estimated altitude every 2 seconds, with the day's minimum and maximum tempera… Beginner
5. 5 Serial Data Logger and Charts Use the whole kit as a data logger: one CSV row of soil, water, temperature, humidity and pressure every few seconds. Paste it into a spreadsheet and… Beginner
6. 6 Optional audible-alert investigation Characterize the buzzer's current, trigger threshold, and active level before choosing a transistor or driver. Write and compile a separate alert ske…
7. 7 Future Wi-Fi dashboard Add networking only after the USB/Serial build is stable. Keep credentials out of shared code and review privacy, reconnection behavior, power, enclo…

The build page is free with the kit: set-up, every project with wiring and steps and code, and a Stuck? box. Every lesson also runs in the online simulator.

Who it's for

Beginner ESP32 kit for building a smart plant monitor and alert system: read soil moisture, check water level, measure temperature and humidity with BME280, and sound a buzzer when the plant needs attention. Designed for students, home makers, and small IoT demos.
