This circuit features an ESP32 Devkit V1 microcontroller interfaced with a VL53L1X time-of-flight distance sensor and controls a 5V relay module, which in turn operates a water solenoid valve. The ESP32 reads distance measurements from the VL53L1X via I2C (using SDA and SCL lines) and can interrupt (INT) or shut down (SHUT) the sensor. The relay module is actuated by the ESP32 to control the power to the solenoid valve, allowing for automated water flow based on the sensor input or other logic programmed into the ESP32.
