DROPLET irrigation system

When PricelessToolkit failed to find an affordable (indoor) irrigation system that works with Home Assistant and ESPHome, he built the DROPLET board based on ESP32 wireless SoC and supporting up to five micro-pumps and soil moisture sensors. The board also comes with switches to manually control the pump, a built-in DS18B20 temperature sensor, a buzzer, and a I/O header to connect an expansion header for relay control, I2C, GPIOs, and an external DS18B20 temperature sensor. DROPLET specifications: Wireless module – ESP32-S with ESP32 dual-core 32-bit microcontroller @ 240 MHz with 2.4 GHz WiFi and Bluetooth connectivity, 4MB SPI flash Display – I2C header for 5V/3.3V OLED display Pump interfaces – 5x 2-pin connectors for micropumps Sensors and sensor interfaces DS18B20 temperature sensor 5x 3-pin connectors for soil moisture sensors; pulled low with a 1 MΩ resistor. Expansion – 2x 16-pin right-angle female header with GPIOs, UART, 5V, and GND Debugging [...]
