Multi-Crop Yield Prediction Edge Node Kit with ESP32 + DHT22
Multi-Crop Yield Prediction Edge Node Kit with ESP32 + DHT22 – Deploy a Solar-Powered LoRa Sensor for Weekly Crop Forecasts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Harness temperature, humidity, soil moisture, NDVI, and rainfall data to feed an LSTM model and generate weekly yield forecasts transmitted via LoRa. This kit turns an ESP32-S3 into a fully autonomous edge node that gives farmers actionable predictions without relying on the cloud.
What You'll Build
An all-weather, solar-powered sensor station that collects environmental and spectral data on your field, runs a trained LSTM model directly on the ESP32-S3, and wirelessly sends crop yield predictions to a remote dashboard. All components mount inside a waterproof enclosure, giving you a production-ready precision agriculture prototype.
What You'll Learn
- Train and quantize an LSTM model for on-device inference on ESP32-S3
- Interface the AS7265x 6-channel spectral sensor to compute NDVI
- Design a solar-powered LoRa transmitter with deep-sleep power management
- Combine DS3231 RTC timestamps with MicroSD logging for analysis

Who This Kit Is For
Advanced B.Tech and M.Tech students from IITs, NITs, VIT, and BITS Pilani building agritech capstone projects; Smart India Hackathon teams focused on boosting farm productivity; and agritech startup engineers prototyping affordable precision farming solutions for Indian monsoon-dependent crops.
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 launch the AI build companion trained precisely on this kit; it understands every connection and model step. If you still need help, message us on WhatsApp — our engineers reply with India-specific advice.
Can I adapt the LSTM model to my own crop and local weather data?
Absolutely. The companion guides you through collecting training data with these sensors and re-training a TensorFlow Lite Micro model for your specific crop variety and micro-climate.
How far does the LoRa signal reach on an Indian farm?
In open fields with the supplied 433 MHz antenna and RA-02 module, expect a reliable range of 1–2 km. Connect the receiving LoRa gateway to a cloud dashboard for farm-wide monitoring.
Will the solar panel and batteries keep the node running during monsoon?
Yes. The 6V 2W panel, dual 18650 cells, and TP4056 charge controller are sized to sustain 24/7 operation even under overcast monsoon skies, with deep-sleep cycles built into the firmware.
Temperature, humidity, soil moisture, NDVI and rainfall fed into LSTM model. Weekly yield forecast via LoRa.
