ESP32-C3 automatic plant watering system using capacitive moisture sensor and DS3231 real-time clock. Logs watering history to Google Sheets document. Configurable and firmware upgradable via standalone WiFi Access Point and webserver.
Using NodeMCU ESP8266 for controlling switches (Relay). Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A webserver for Manual Controls. Vast application including Aquariums and IOT related.
DS2321 Driver for Pi Pico
RP-Pico C library for DS3231 RTC module.
The project integrates an Arduino with a DHT11 sensor for measuring temperature and humidity, along with an RTC DS3231 module for maintaining real-time clock functionality. The Arduino periodically reads data from the DHT11 sensor and RTC module, calculates the heat index, and sends all data (including date, time, temperature, and humidity)
