Wireless Perimeter Alarm Network Kit with Arduino Nano + NRF24
Wireless Perimeter Alarm Network Kit with Arduino Nano + NRF24 — Build a Multi-Zone Security System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll build a reliable wireless alarm network that monitors four independent zones — each node combining a PIR motion sensor and a reed switch for doors, windows, or gates. When an intrusion is detected, the central panel instantly shows the zone on an LCD and sounds the alarm, just like commercial security systems.
What You'll Build
A fully functional 4-zone wireless security alarm system. The central console displays real-time zone status on a 16x2 LCD, armed/disarmed via a master switch, and triggers a loud active buzzer on breach. Each remote sensor node operates on battery power (9V) and communicates via NRF24L01 transceivers, making it portable and easy to deploy around a campus, hostel, or maker lab.
What You'll Learn
- Wireless communication protocols with NRF24L01 modules, including addressing, payload encoding, and power management.
- Integrating PIR motion sensors and magnetic reed switches for intrusion detection and debouncing.
- Designing a multi-node alarm panel with zone identification, armed/disarmed logic, and real-time display on I2C LCD.
- Building power-efficient battery-operated Arduino Nano sensor nodes with capacitor filtering to suppress noise.

Who This Kit Is For
Ideal for B.Tech ECE/EEE students (2nd–3rd year) building a capstone wireless sensor network project or preparing for Smart India Hackathon. Also fits IIT, NIT, VIT, BITS campus security challenges and advanced makerspaces wanting a reliable multi-zone alarm demonstration for workshops.
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?
Our AI build companion, accessed via QR code or WhatsApp, provides step-by-step assistance for this exact project. You can also reach us on WhatsApp for human help.
Does this kit require soldering?
Yes, the sensor nodes and central panel are built on prototyping PCBs using the included soldering iron and solder. Some basic soldering experience is recommended, but the AI guide covers all connections.
Can I expand the system to more than four zones?
The Arduino Nano central panel can be programmed to support additional NRF24L01 nodes with address modifications. The kit includes 5 Nanos, so you can prototype a 5th node immediately.
What kind of range can I expect?
With the included PCB antenna NRF24L01 modules, expect 50–100 meters open-air range, sufficient for a small campus perimeter, large home, or hostel wing.
Four NRF24L01 sensor nodes report PIR and reed switch state to a central alarm panel with zone display.
