Weather&Humidity Clock
Weather Clock with Humidity Sensor
A one line project description
Author: Matache Monica Magdalena GitHub Project Link:https://github.com/UPB-PMRust-Students/project-monica282004
Description
An interactive monitoring system using Raspberry Pi Pico. It displays the current time, date, temperature, and humidity on an ST7735S LCD. Data is updated in real-time whenever motion is detected by the PIR sensor
Motivation
To create a smart, real-time environmental monitor that responds to human presence. It combines timekeeping, weather, and motion detection in one compact system. The project aims to enhance awareness of surroundings efficiently.
Architecture
Raspberry Pi Pico – Microcontroller that coordinates sensors, display, and logic.
RTC DS3231 – Real-time clock module providing accurate date and time.
DHT22 – Temperature and humidity sensor for environmental monitoring.
ST7735S LCD – Small color display to show time, date, weather, and humidity.
PIR HC-SR505 – Motion sensor that triggers updates when movement is detected.

Hardware
In my project, the Raspberry Pi Pico microcontroller serves as the central processing unit, mandated for the task. Its low power consumption ensures efficiency throughout. It also reads data and time from the DS3231 real time clock module and DHT22 Sensor and displays them, while also being able to send electrical signals to a motion sensor for an alarm effect.
