ESP32 PIR WiFi Alert Kit with ESP32 + LED
ESP32 Motion Alert System: Get Instant WiFi Push Notifications When Motion Detected
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a project that sends a silent alert to your phone every time someone enters your room. This kit makes that real — you'll wire a PIR sensor and LEDs to an ESP32, then program it to ping Pushover or IFTTT instantly over WiFi. No soldering, no prior experience with microcontrollers needed. Just follow the guided build and watch your security sensor live.
What You'll Build
A fully functional motion alert station. The HC-SR501 PIR sensor detects movement, the red LED flashes while the green LED stays steady, and within seconds your smartphone receives a push notification. Tweak sensitivity and delay directly on the sensor, then mount it on a breadboard chassis you design. It’s a real IoT device you’ll keep on your desk or door frame.
What You'll Learn
- How PIR sensors use infrared heat signatures to detect people and how the HC‑SR501’s time and sensitivity potentiometers work
- Connecting digital and analogue components comfortably on a 400‑point breadboard without short circuits
- Programming the ESP32 in Arduino IDE to connect to your home WiFi and trigger webhook requests
- Basic electronics maths: why 220 Ω and 10 kΩ resistors protect LEDs and stabilize sensor inputs

Who This Kit Is For
CBSE Class 11–12 students exploring IoT in computer science, ATL Tinkering Lab participants building a smart security prototype, and B.Tech ECE/EEE freshers looking for a first mini project. Young learners aged 10+ can assemble it with an adult nearby; the schematics and AI companion keep every step clear. Even Smart India Hackathon teams use this kit to quickly demo real‑time alert systems.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to open the AI companion; it diagnoses common wiring and code mistakes. Still stuck? Send a photo to our WhatsApp support — we respond within hours.
Do I need a smartphone for the push notifications?
Yes, you’ll install the free Pushover or IFTTT app on any Android or iOS phone. The guide walks you through creating a free account and generating the webhook keys.
Can I use this kit for a CBSE science exhibition?
Absolutely. The motion‑triggered alert is a clear demonstration of IoT and sensor integration, and the build log helps you write a strong project report.
What if my home WiFi is 5GHz only?
The ESP32 onboard chip works with 2.4GHz networks, which nearly every router still broadcasts alongside 5GHz. Check your router’s settings if you only see one network name.
PIR detects motion and ESP32 sends push notification via Pushover or IFTTT over WiFi immediately.
