Raspberry Pi Pico Smart Home Automation System

Overview

This repository contains the Python script for a smart home automation system implemented on a Raspberry Pi Pico board. The system utilizes GPIO pins for controlling devices such as fans and LEDs, and it communicates with other devices via UART.

Hardware Requirements

• 1x Raspberry Pi Pico
• 1x Micro USB cable
• 1x HC 05 Bluetooth module
• 2x LED
• 2x Fans
• 1x Ultrasonic Sensor
• Jumper wires
• 2x 1x20 male header pins (for the Pico)

Features

• Ultrasonic Sensor (USS): Measures distance and controls bedroom fan and light based on proximity.
• UART Communication: Listens for commands through UART to control various devices.
• Device Control: Controls bedroom fan, hall fan, bedroom LED, and hall LED based on received commands.
• Automation Logic: Implements basic automation logic for turning on/off devices based on conditions.

Getting Started

Prerequisites

• Raspberry Pi Pico board
• Micro USB cable
• MicroPython firmware installed on the Raspberry Pi Pico

How to run

• Upload the Python script to your Raspberry Pi Pico board.

• Connect the required devices (fans, LEDs, ultrasonic sensor) to the corresponding GPIO pins based on the script. Bedroom Fan: GPIO 15

  Hall Fan: GPIO 14

  Bedroom LED: GPIO 16

  Hall LED: GPIO 18

  Ultrasonic Sensor Signal Pin: GPIO 0- Power up the Raspberry Pi Pico.

• Customize the script or UART commands based on your specific setup and requirements.

Usage

• Ensure that the Raspberry Pi Pico is powered and the script is running.

• Send commands through UART to control devices. Example commands:

  To turn on the bedroom fan: bedroom fan on

  To turn off all devices: turn off

• Monitor the console output for distance measurements from the ultrasonic sensor.

UART Commands

• bedroom fan on: Turn on the bedroom fan.
• bedroom fan off: Turn off the bedroom fan.
• hall fan on: Turn on the hall fan.
• hall fan off: Turn off the hall fan.
• bedroom light on: Turn on the bedroom LED.
• bedroom light off: Turn off the bedroom LED.
• hall light on: Turn on the hall LED.
• hall light off: Turn off the hall LED.
• lights on: Turn on both bedroom and hall LEDs.
• lights off: Turn off both bedroom and hall LEDs.
• fans on: Turn on both bedroom and hall fans.
• fans off: Turn off both bedroom and hall fans.
• all devices: Turn on all devices (fans and LEDs).
• turn off: Turn off all devices (fans and LEDs).
