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.
Battery-powered e-paper sign: room signage, sensor graphs, home automation, or anything over Wi-Fi. Wakes by real-time clock, NFC tap, or button. Raspberry Pi Pico W firmware, custom PCB, and 3D-printed case included.
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.
RP-Pico C library for DS3231 RTC module.
DS2321 Driver for Pi Pico
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)
