Long Range Farm Sensor Node Kit with Arduino Nano + LoRa
Build a Solar-Powered LoRa Borehole Monitor with Arduino Nano — Long-Range Farm Sensor Node Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Walking across acres every day just to check a borehole’s water level and pump rate isn’t just tiring — it delays decisions that cost crops. This kit gives you the hardware to build a long-range sensor network that transmits groundwater depth and flow data wirelessly, allowing you to monitor from a central point on the farm. Designed for Indian farm conditions, the system runs on solar power and uses LoRa to reach distant boreholes, so you can irrigate with confidence based on real numbers, not guesswork.
What You'll Build
You’ll assemble two Arduino Nano boards into a transmitter-receiver pair: the outdoor node at the borehole contains the submersible pressure sensor and YF-S201 flow sensor, while the indoor receiver logs data. The transmitter reads water depth up to 10 metres and flow rate in litres per minute, timestamps every reading with the DS3231 RTC, stores it on the microSD module, and sends the data packet over LoRa. Up to 2 km away (line-of-sight), the receiver displays the latest values and saves history for crop planning.
What You'll Learn
- Calibrate and install a submersible pressure sensor for continuous depth measurement
- Integrate a YF-S201 flow sensor to track pumping rate and total water extracted
- Configure RA-02 LoRa modules for reliable 433 MHz communication over kilometres
- Design a solar charging circuit with TP4056, 18650 cells, and a 6V panel for 24/7 off-grid operation

Who This Kit Is For
This kit suits farmers and agri-entrepreneurs moving to precision irrigation, B.Tech Agricultural Engineering and ECE students prototyping smart water projects, Smart India Hackathon teams tackling groundwater challenges, and ATL Tinkering Labs demonstrating IoT in agriculture. You should be comfortable with soldering and basic Arduino coding; no prior LoRa experience is needed — the AI companion walks you through every step.
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, we'll replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion — it’s been trained on this precise hardware and will guide you through wiring and code. For extra help, send a photo on WhatsApp and our support team will troubleshoot with you directly.
How far can the LoRa signal reach on a farm?
In open fields with the included 433 MHz antennas, expect a reliable range of 1 to 2 kilometres. Placing the transmitter on a small mast above crop height improves line-of-sight; dense tree cover or buildings will shorten distance, but the node can be positioned for maximum coverage.
Can the sensor node handle monsoon rains and submerged operation?
Yes, the submersible pressure sensor is built to stay underwater permanently. The electronics are housed in the IP65 waterproof enclosure — after wiring, seal the cable gland with silicone for full weather protection so the node runs safely through heavy rain and humidity.
Can I connect this to a farm management app or cloud dashboard?
The receiver logs all data to microSD card; you can export the CSV files to any analytics tool. For live cloud access, the receiver’s serial output can feed into a Raspberry Pi or ESP32, enabling push to platforms like ThingSpeak, Blynk, or AWS IoT.
