Tropical Cyclone Pressure Drop Monitor Variant 4
Arduino Cyclone Pressure Drop Monitor Kit — Build an SMS Storm Alert System for Coastal Safety
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Cyclones claim hundreds of lives on India’s coasts every year — often with little warning. This kit lets you assemble a functional early-warning station that tracks atmospheric pressure fall rates and sends SMS alerts when conditions match tropical storm signatures. It’s an advanced project designed for engineering students, researchers, and disaster-mitigation innovators who want a hands-on understanding of real-time environmental monitoring.
What You'll Build
A self-contained weather-proof monitor that logs barometric pressure to an SD card with precise timestamps from the DS3231 RTC. When the BMP280 sensor detects a pressure drop exceeding 3 hPa per hour (a tropical cyclone hallmark), the SIM800L GSM module instantly dispatches an SMS alert to a predefined phone number. The system displays real-time pressure, fall rate, and alert status on a 0.96-inch OLED screen, all housed in a waterproof enclosure for outdoor deployment.
What You'll Learn
- Calibrating a BMP280 barometric sensor for high-resolution pressure tracking
- Programming rate-of-change algorithms to trigger SMS alerts via SIM800L GSM
- Logging time-stamped sensor data to an SD card using the DS3231 real-time clock
- Integrating a buck converter to ensure stable power for an outdoor, always-on monitoring unit

Who This Kit Is For
This advanced kit is built for engineering students (B.Tech ECE/EEE) at universities like IITs, NITs, VIT, and BITS Pilani working on disaster-mitigation or IoT-based environmental projects. It also supports Smart India Hackathon problem statements on coastal safety, and research scholars setting up pressure-monitoring grids in cyclone-prone states like Odisha and Tamil Nadu.
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 kit box and start a conversation with our AI companion, which has been fine-tuned on this exact cyclone monitor project. If you need human help, a WhatsApp message to our support team gets you unstuck within hours.
Can I deploy this outdoors in monsoon conditions?
Yes, the included IP65 waterproof enclosure is designed for outdoor use. The LM2596 buck converter accepts a wide input range (up to 24V) so you can power the unit from a 12V lead-acid battery; just seal cable glands with silicone and place the enclosure under a small shelter for added longevity.
Does the kit include a SIM card for the GSM module?
No, you need to insert a 2G-enabled SIM with an SMS plan. Airtel and Vodafone still support 2G in many coastal zones — we recommend testing with a local prepaid card before permanent deployment.
How accurate is the BMP280 for cyclone detection?
The BMP280 offers ±1 hPa absolute accuracy. Our algorithm tracks the rate of pressure change over a rolling window and triggers an alert when the drop exceeds a configurable threshold (default 3 hPa/hr), which closely matches tropical storm signatures observed by IMD. Proper calibration in the build process ensures reliable early warning.
BMP280 logs rate of pressure fall. Alerts if fall rate exceeds tropical storm threshold.
