    ...pressure switch. But unfortunately, I do not have enough knowledge about ESP32 WiFi myself and this is beyond my personal skills. How the pressure switch currently operates: - Pressure switch consists of the pressure plate and a tri-colour LED. - Switch connects to a mobile app via Wi-Fi SSID and Password (both are known) - The App displays the pressure switch’s ID name, IP address, MAC address, battery level, etc - When the pressure switch is activated (tapped) the LED changes colour and it sends data to the app I have built a simple sketch, via the Arduino IDE ESP32 WiFi examples, to connect to the pressure switch and successfully print the connection status and IP address to the serial monitor. Scope of this project: I need a simple ESP32 sketch that connects to the p...

Board will have 6 different isolated 24V DC outputs, these outputs will be able to supply 1A of current typically and 1.2A on burst condition. Also there will be 5V 3A and 3.3V 1A non-isolated outputs. There will be 2x 12V Lead-Acid battery connection for backup the mains input. Power supply will be controlled with an integrated microcontroller and will support security functions. Design will be performed with avoiding obsolete parts and will utilise SMD technology. In the first stage, detailed system plan needed prior to elecrical design.

    This project is two fold as you look at the schematic- piezo and metal tank. The suggest is made of placing a second inductor across the primary of the transformer to improve the driver's efficiency . The value of the inductor is empirically picked to minimize power consumption (it offsets some of the capacitance of the piezo transducer. The optimization need to function with any piezo at the 63kHz range Also we consider a push/pull transformer arrangement driven by a similar microprocessor arranged input. This is typical of higher power ultrasonic drivers.
