Building a self-watering plant using Micropython on a WiFi-enabled Arduino ESP8266
summary
A working self‑watering system runs on an ESP8266 running MicroPython, reads a capacitive soil moisture sensor over the ADC, averages ~10 samples, and checks every 15 minutes; if moisture falls below 70% threshold it pulses a submerged pump via a transistor for 3 seconds, uploads readings to Ubidots and posts a Slack alert. Firmware is flashed with esptool, files managed with mp/WebREPL, and a power bank solves intermittent power failures.
