ESP32 Wireless Garden Monitoring Kit: 5 Nodes, DHT22, ESP-NOW
ESP32 Wireless Garden Monitoring Kit - 5 Node ESP-NOW Network with DHT22, Soil Moisture, and TFT Gateway
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your garden into a data-driven powerhouse. This kit puts you in the role of IoT architect, building five battery-powered sensor nodes that measure soil moisture, temperature, and humidity. They whisper their data over ESP-NOW to a gateway ESP32, which renders every reading on a crisp 1.8-inch TFT. It's a real-world wireless sensor network, exactly what you'd deploy in smart agriculture projects.
What You'll Build
A complete, multi-zone garden monitoring network. Each node is a standalone unit with its own 18650 cell, DHT22, and capacitive soil moisture sensor, sleeping deeply to preserve battery for weeks. The gateway node acts as the brain, receiving all five data streams and cycling through them on the ST7735 display. You'll walk away with a system you can expand, replicate, and showcase in capstone demos.
What You'll Learn
- Design and implement low-power ESP-NOW peer-to-peer communication across multiple ESP32 boards
- Interface capacitive soil moisture sensors and DHT22 humidity/temperature sensors for environmental monitoring
- Manage deep sleep and wake cycles on battery-powered nodes to maximise 18650 cell life
- Code a TFT dashboard that rotates through sensor data with smooth visual transitions

Who This Kit Is For
B.Tech ECE, EEE, and CSE students building IoT capstone or Smart India Hackathon projects will find this kit purpose-built for precision agriculture challenges. ATL Tinkering Lab mentors guiding advanced students can use it to teach wireless networking fundamentals. Makers comfortable with Arduino IDE who want to leap from single-sensor setups to a true ESP-NOW mesh will appreciate the structured, hands-on challenge. It's also a strong fit for IIT, NIT, VIT, and BITS Pilani coursework in embedded systems.
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 your AI build companion trained on this exact kit; it provides step-by-step debugging, wiring checks, and code explanations. If you still need help, message us on WhatsApp for personal assistance.
Can I scale this network to more than five nodes?
Absolutely. ESP-NOW supports up to 20 peers, and the gateway code is designed with modular address handling. The kit teaches you the architecture so you can add additional soil, light, or water flow sensors by expanding the project.
Do the sensor nodes come pre-soldered?
No, this is an advanced hands-on kit. You'll receive all parts unsoldered, including the PCB prototype boards, connector headers, and the soldering iron. Soldering the nodes together is a core part of the build experience, reinforcing circuit assembly skills.
How long do the 18650 batteries last per charge in the sensor nodes?
With deep sleep routines and periodic wake-ups every 5 minutes, a single 18650 cell can power a node for several weeks. The AI companion provides optimized power profiles and guidance on adjusting sleep intervals for your garden's needs.
Garden - Five ESP32 sensor nodes transmit to one gateway node over ESP-NOW. Gateway aggregates and displays all readings on TFT.
