Crop Rain Monitor for Farms Kit
Crop Rain Monitor Kit: Build Your Own ESP32-Powered Farm Weather Station
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 raw farm data into actionable insights. This kit lets you build a solar-rechargeable, IP65-enclosed station that streams real-time rainfall, temperature, humidity, atmospheric pressure, and UV index to a cloud-hosted Grafana dashboard — no more guessing when to irrigate or protect crops from weather extremes. Perfect for agricultural decision-making across India's diverse climate zones.
What You'll Build
A rugged, field-deployable weather monitor that publishes sensor readings via MQTT to an InfluxDB time-series database. Your live Grafana dashboard visualizes historical rainfall patterns, temperature trends, and UV exposure — all accessible from a smartphone or laptop on the farm. The kit includes everything to solder and assemble a self-contained, battery-powered unit that can run outdoors for days.
What You'll Learn
- Integrate DHT22, BMP280, ML8511, and rain sensor with ESP32 over I2C and analog GPIO
- Configure an MQTT broker and InfluxDB cloud instance to receive and store environmental data
- Build a real-time Grafana dashboard with rainfall gauges, temperature charts, and UV index panels
- Design a solar-powered, battery-backed system with LM2596 converter and TP4056 charging for 24/7 operation

Who This Kit Is For
Agricultural entrepreneurs building on-farm monitoring networks, B.Tech Agricultural Engineering students at universities like TNAU or IIT Kharagpur working on Smart India Hackathon projects, and ATL tinkering lab facilitators designing rural IoT deployments. Ideal for anyone who wants a professional-grade weather station tailored for Indian cropping patterns.
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 to chat with the AI companion that has every wire, code snippet, and troubleshooting step for this kit. You can also reach a real builder over WhatsApp for extra guidance.
Do I need a cloud subscription for InfluxDB and Grafana?
We provide a step-by-step guide to set up a free-tier InfluxDB Cloud account and Grafana instance. The AI companion will walk you through configuration, so no paid subscription is needed to get your dashboard live.
Can this kit run off-grid on a farm?
Absolutely. The 18650 cells, TP4056 charging module, and LM2596 converter let you connect a small solar panel (not included) for continuous outdoor operation. The waterproof enclosure protects everything from rain and dust.
How do I interpret the dashboard data for crop decisions?
The Grafana dashboard includes pre-configured panels with thresholds; you can set alerts for heavy rainfall or low humidity to trigger irrigation or crop protection measures. The AI companion explains each metric and its agricultural relevance.
