ESP32 Industrial Water Shutoff Kit with 8 Sensors & Relay
ESP32 Industrial Water Shutoff Kit with 8 Sensors & Relay
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Industrial water leaks can stop production lines cold. With this kit, you build a wireless 8-zone leak detection network that automatically closes a solenoid valve the moment any sensor reports moisture - exactly the kind of failsafe demanded in factories, greenhouses, and process plants across India.
What You'll Build
Eight self-contained Arduino Nano sensor nodes, each powered by an 18650 cell and communicating over 2.4GHz NRF24L01 radios, relay moisture events to a central ESP32 hub. The hub continuously monitors all nodes and, on the first alert, energises the 5V relay module to shut off a mains solenoid valve. A 30-capacitor filter bank ensures rock-steady power even with fluctuating battery levels, making the network suitable for long-term deployment in harsh locations.
What You'll Learn
- Build a low-power wireless sensor mesh using Arduino Nano and NRF24L01 modules
- Program an ESP32 as a multi-channel receiver and actuator controller
- Design battery-operated remote nodes with TP4056 charge management
- Integrate industrial relay logic for real-world water shutoff automation

Who This Kit Is For
B.Tech ECE and EEE students tackling final-year projects, Smart India Hackathon teams prototyping industrial IoT solutions, and ATL tinkering mentors looking for a challenging automation build will find this kit directly relevant. The 8-zone architecture mirrors real-world factory floor monitoring requirements, making it a strong portfolio piece for IIT, NIT, VIT, and BITS Pilani students.
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 launch the AI build companion, which walks you through wiring, code upload, and troubleshooting for this specific network of eight sensors. WhatsApp support from our Bengaluru team is also available for trickier challenges.
Do I need to solder anything?
Yes, all 9 prototype boards (one per node and one for the hub) require soldering to mount the modules and capacitors. A temperature-controlled soldering iron and lead-free solder wire are included, and the AI guide demonstrates joint techniques for the NRF24L01 radio pin headers.
Can I expand the system beyond eight water sensors?
The hub's software is designed for up to 16 unique node addresses. With additional Arduino Nanos and sensors (not included), you can scale the network. The RF channel assignment is documented in the build guide to avoid collisions.
What type of solenoid valve does this kit control?
The relay module can switch any normally closed solenoid valve rated for the relay's 10A/250V contacts. For a typical �-inch or �-inch water line, a 12V DC solenoid valve works well - you'll need to supply its separate power source; wiring instructions are provided.
Industrial Automation - Eight water sensors via ESP-NOW report to hub. Hub triggers solenoid valve shutoff on any detection.
