RF Jammer Detection Alarm Variant 9 Kit with ESP32 + LoRa
Build a Professional RF Jammer Detection Alarm System with ESP32 + LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In an era where wireless communication can be disrupted by malicious RF jammers, building a detection system that alerts you instantly is a vital skill. This kit lets you assemble a standalone alarm unit that senses continuous-wave and pulsed jamming across 433 MHz, triggers a loud buzzer, logs the event on an OLED, and notifies you via GSM—even if primary networks are jammed. Perfect for securing sensitive installations or for advanced engineering projects.
What You'll Build
A self-contained surveillance device that monitors RF background noise using an RCWL-0516 Doppler radar module and a LoRa radio acting as a software-defined spectrum analyzer. When a jamming signature—a sudden, sustained rise in RSSI on the 433 MHz band—is detected, the ESP32 activates a piercing alarm and sends an SMS alert through the SIM800L module. The OLED display shows real-time RSSI values and jammer status. The unit is housed in a rugged enclosure, powered by a stable 5V supply.
What You'll Learn
- Interfacing the RCWL-0516 radar sensor for motion and presence detection in an RF security context.
- Using RA-02 LoRa module to measure radio frequency signal strength (RSSI) and identify jamming patterns.
- Integrating SIM800L GSM for SMS alerts and understanding AT command communication.
- Designing power regulation with a buck converter, decoupling capacitors, and PCB prototyping for noise-sensitive RF circuits.

Who This Kit Is For
This advanced kit suits engineering students, cybersecurity researchers, and electronics professionals who need to prototype RF threat detection systems. Specifically, it aligns with B.Tech ECE/EEE final-year projects, defence technology hackathons like Smart India Hackathon, and ATL Tinkering Lab extensions. Indian institutes like IITs, NITs, VIT, and BITS often use such kits for capstone projects on communication security.
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 on the box to access the AI companion, which offers step-by-step debugging. You can also send a photo or query via WhatsApp, and our team will respond within hours.
Does this kit detect all types of RF jammers?
The kit is tuned to detect continuous and pulsed jamming in the 433 MHz ISM band, which is common for consumer device jammers. It uses RSSI thresholding with the RA-02 LoRa module; adjusting the threshold in code can adapt to different jammer signatures.
Can I use this for my college project documentation?
Yes. The AI companion provides build logs, circuit diagrams, and code explanations that you can include in your project report. We also offer schematic PDFs upon request.
What if a component fails after assembly?
Compoden offers a 7-day replacement for manufacturing defects. Contact WhatsApp support, and we will ship a replacement within 48 hours.
RCWL-0516 radar + RA-02 LoRa RSSI monitor detect RF jamming attempts and trigger local alarm + GSM backup alert.
