Original Description:
Daddy's second circuit board. A sign to let my wife know when I'm on a call. Activates with a slide switch and is powered by USB-C.
ESP32 DevKit V1 sensor hub powered from a 12V barrel jack through an LM2596 5V buck converter, with gas, temperature, flame, thermal camera, OLED, relay outputs, buzzer, and ESP32-CAM connections.
ESP32-based motor controller using a buck converter and SparkFun TB6612FNG motor driver, with a 2-terminal DC motor placeholder for the JGA25-371 gearmotor.
ESP32-centered controller PCB with 14.8 V battery bus, external 3.3 V and 12.2 V buck converter interfaces, motor logic headers, and servo driver connections.
This project is designed to measure water level of two tanks using ultrasonic sensors interfaced with the ESP32 microcontroller. The design leverages the processing power and wireless connectivity of the ESP32 to accurately monitor water levels and support automated water management processes. Key components include two ultrasonic sensors for precise distance measurement, robust voltage regulation using an LM2596 buck converter, and reliable power management circuits. Its modular design approach facilitates easy expansion and integration with other systems, making it an ideal solution for both DIY enthusiasts and professionals in automated fluid control and IoT applications.
