Flood Detector Pump Controller Kit with Arduino Uno + Sensor
Arduino Flood Detector & Pump Controller Kit with SMS Alerts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Water damage in basements, storage rooms, or during monsoons can ruin belongings and equipment. This kit lets you build a reliable flood detector that automatically triggers a water pump when water is sensed, and simultaneously sends an SMS alert via the SIM800L GSM module. It's a complete home automation solution with immediate real-world utility — and you’ll learn core concepts of sensor integration, relay control, and GSM communication.
What You'll Build
A working embedded system that sits on the floor: when the water sensor probes detect moisture, the Arduino turns on a relay to activate an external pump, and sends an SMS to your phone. You'll place two water sensors at different levels for staged alerts, and use indicator LEDs to show system status. It's a compact, deployable unit ready for home or school use.
What You'll Learn
- Reading analog water sensors with Arduino
- Controlling a high-power pump via a 5V relay safely with diode protection
- Sending SMS using SIM800L GSM module and AT commands
- Integrating power management with a buck converter for stable voltages

Who This Kit Is For
Ideal for high school students (CBSE Class 11-12) working on electronics projects, B.Tech ECE/EEE students building mini-projects, and participants in Smart India Hackathon or ATL Tinkering Labs. Also suitable for hobbyists in IIT, NIT, VIT, or BITS Pilani who want a ready-to-assemble flood monitoring system with GSM integration.
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 inside the box for your AI build companion, which walks you through every step for this exact kit. WhatsApp and email support are also available from Compoden.
Can I use this kit with a 12V water pump?
Yes. The 5V relay module can switch loads up to 250V AC or 30V DC, so connecting a 12V pump is straightforward. The kit includes a buck converter to power the Arduino and SIM800L from a common 12V supply if needed.
Does the SIM800L work with all Indian mobile networks?
The SIM800L operates on 2G GSM bands 850/900/1800/1900 MHz, which are still active in India (Airtel, Vi, BSNL). Ensure you use a 2G-capable SIM and adequate signal.
Can I add more water sensors for larger area coverage?
Absolutely. The Arduino Uno has multiple analog inputs, so you can connect additional water sensors and modify the code to handle them. The AI companion can help with code changes.
Water sensor on floor triggers relay pump to drain water. SMS alert via SIM800L simultaneously.
