ESP32 Greenhouse Monitoring Kit: Soil & Climate Sensor Network
Build a Smart Greenhouse: ESP32 Sensor Network Kit for Soil and Climate Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking into your greenhouse and seeing real-time soil moisture, temperature, and humidity from five different zones on a single colour display - no cloud, no Wi-Fi router, just a private wireless network that you built. That's exactly what this kit delivers. Designed for engineering students, agri-tech tinkerers, and Smart India Hackathon contenders, it transforms six ESP32 microcontrollers into a ready-to-deploy environmental monitoring system.
What You'll Build
A distributed sensor array powered by five battery-operated nodes that capture DHT22 climate readings and soil moisture data. Each node talks to a central gateway over ESP-NOW, a low-latency protocol built into the ESP32. The gateway aggregates every reading and paints them live on a 1.8-inch TFT screen - a true hands-on experience in scalable wireless sensor networks.
What You'll Learn
- Configure ESP-NOW peer-to-peer communication between multiple ESP32 boards
- Read precision temperature, humidity (DHT22), and capacitive soil moisture sensors
- Manage 18650 Li-ion power with deep sleep for long-term field deployment
- Drive an SPI colour TFT display and render real-time data dashboards

Who This Kit Is For
B.Tech ECE/EEE students crafting capstone projects will gain hands-on IoT networking experience. Smart India Hackathon teams can prototype precision agriculture solutions in hours. ATL Tinkering Lab mentors can challenge advanced learners with real wireless sensor deployment, while IIT, NIT, VIT, and BITS Pilani enthusiasts get a complete platform for ESP-NOW experimentation and TFT dashboard development.
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 chat with the AI companion trained on this kit's code and wiring. If you need human help, our WhatsApp support line responds within hours.
Can I increase the number of sensor nodes later?
Yes, the gateway firmware uses device MAC addresses for identification. The AI companion can walk you through adding up to 10 nodes without altering the hardware.
Does the kit require internet or a Wi-Fi router?
No. ESP-NOW creates a direct, offline wireless network between the ESP32 boards. The gateway displays all data locally on the TFT screen; internet is only needed if you later choose to upload readings to a cloud server.
I have never soldered before. Is that okay?
This advanced kit assumes basic soldering skills. The included iron and lead-free wire are adequate, and the AI companion offers clear soldering tips. If you are completely new, we recommend practicing on spare PCB beforehand.
Greenhouse - Five ESP32 sensor nodes transmit to one gateway node over ESP-NOW. Gateway aggregates and displays all readings on TFT.
