Greenhouse Climate Monitor Kit v11
Build a 1km Range Greenhouse Climate Monitor with ESP32 and LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn an ESP32 into a wireless greenhouse sentinel that transmits real-time temperature and humidity data to a receiver 1km away. Using the RA‑02 LoRa module, you’ll create a point‑to‑point link that works without WiFi, cellular, or any recurring subscription — ideal for remote farm monitoring, polyhouse automation, or B.Tech ECE projects.
What You'll Build
A battery‑operated sensor node that reads DHT22 climate values and sends them over LoRa to a gateway. On the receiving side, you'll view live serial data or route it to a dashboard. By the end, you’ll have a functional prototype that demonstrates long‑range wireless sensing for agriculture — ready for field deployment or your next hackathon demo.
What You'll Learn
- Configure the RA‑02 SX1278 LoRa module for peer‑to‑peer communication on the ESP32
- Interface the DHT22 sensor to capture precise temperature and humidity readings
- Design a stand‑alone sensor node that draws minimal power for extended battery life
- Troubleshoot packet loss, antenna orientation, and wireless parameters like spreading factor

Who This Kit Is For
CBSE Class 11–12 students building sensor‑network projects for science exhibitions, B.Tech ECE/EEE undergraduates working on IoT and wireless communication labs, and Smart India Hackathon teams prototyping remote agriculture solutions. It’s equally suited for ATL Tinkering Labs demonstrating real‑world LPWAN applications, and for hobbyists who manage polyhouses or small farms.
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?
Open the QR‑linked AI companion for real‑time diagnosis of wiring, code libraries, and LoRa parameters. If you still need help, WhatsApp us a photo of your breadboard and our support team will respond within hours.
Can I increase the range beyond 1km?
Yes, by using a higher‑gain antenna or adjusting the spreading factor in the sketch. The RA‑02 module supports configurations that trade data rate for range; the companion app explains safe limits for India’s sub‑GHz band.
Do I need two kits for a transmitter and receiver?
The kit includes one complete sensor node. To build a gateway, you’ll need a second ESP32 and RA‑02 module (available separately), along with the same wiring. The AI companion covers both ends of the link.
Is this project suitable for a CBSE science fair?
Absolutely. The long‑range wireless aspect and agricultural relevance make it a standout entry. The companion app provides documentation suitable for project reports and viva‑voce.
