Pico Sensor and Controller Circuit
This circuit will have a collection of sensors that will capture data. The Pico will read the data and display it on the LCD, send it to the ESP32 over UART, and write the data to the default Serial port so that it can be read by the Node-RED flow.
The ESP32 communication circuit will publish the sensor data to the MQTT broker from where it will be read by the mobile app.
This circuit will also have a collection of relays and motors that will receive control signals from the ESP32 communication circuit over UART and over the default Serial port from the Node-RED flow.
