How It Works

This IoT-based project establishes a continuous monitoring system using a Raspberry Pi Pico W microcontroller and an infrared (IR) sensor mounted on a breadboard with connecting wires. The IR sensor operates by emitting infrared light and detecting any reflection caused by an obstacle or person entering its detection zone. When the sensor detects a trigger, it outputs a digital signal to one of the General Purpose Input/Output (GPIO) pins on the Raspberry Pi Pico W. Utilizing its onboard Wi-Fi capabilities, the Pico W connects to a local wireless network and executes a script programmed via the Arduino IDE or a MicroPython environment. This script includes Wi-Fi and WiFiClientSecure libraries to securely interface with the CircuitDigest Cloud API over HTTP or HTTPS protocols. Upon receiving the digital state change from the IR sensor, the microcontroller sends an API request to the cloud service, which subsequently triggers and dispatches an instant email notification to the user's designated inbox. The entire workflow bridges physical hardware detection with cloud-based communication without requiring complex external modules.

Why Build This

Design and prototype a practical undergraduate-level IoT security node that bridges physical edge sensors with cloud-based messaging APIs.

Implement network communication protocols on a microcontroller to send automated, remote alerts over standard Wi-Fi infrastructure.

Develop reliable trigger-action automation logic suitable for deployment in automated intrusion detection and entry-monitoring applications.

Real-World Application

Intrusion detection systems, home security monitoring, office and warehouse entry alerts, and remote environmental surveillance.

Frequently Asked Questions

Can I use a standard Raspberry Pi Pico instead of the Pico W?

No, this specific project requires the Raspberry Pi Pico W because it features an onboard wireless chip necessary to connect to Wi-Fi and communicate with the CircuitDigest Cloud API.

What programming environment should I use for writing the code?

You can use either the Arduino IDE or a MicroPython-compatible environment, provided you install the necessary Wi-Fi and secure client libraries.

How does the IR sensor know when to send an email?

The IR sensor detects motion or an object in its field of view, changes its digital output state, and the Pico W reads this change to trigger an API request that sends the email.
