Hydroponics Nutrient Monitor Kit v6
Hydroponics Nutrient Monitor Kit v6 – Remote LoRa Sensing with Arduino, Solar-Powered and Field-Ready
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In hydroponics, the root environment is everything. This kit lets you build a rugged, solar-powered sensor node that measures moisture and temperature in your growing medium, then transmits that data over LoRa every 10 minutes — a powerful project for school science fairs, smart agriculture prototypes, or your own home hydroponics setup.
What You'll Build
You’ll assemble the Arduino Nano, RA-02 LoRa module, two soil moisture sensors, and a waterproof DS18B20 temperature probe onto a custom PCB prototype board. The solar panel and TP4056 charging module keep the dual 18650 cells topped up, so the node operates off-grid indefinitely. Sealed inside a waterproof enclosure, it’s ready to sit among your hydroponic beds, gathering data and sending it wirelessly.
What You'll Learn
- Soldering and assembling a multi-component embedded system on a PCB prototype board
- Configuring and coding the RA-02 LoRa module for 433 MHz transmission
- Interfacing capacitive soil moisture sensors and a DS18B20 temperature probe with Arduino
- Designing a solar power management circuit using the TP4056 and 18650 lithium cells

Who This Kit Is For
Tailored for CBSE Class 11-12 students building a physics or computer science investigatory project, B.Tech ECE/EEE undergraduates prototyping a farm‑monitoring system, teams preparing for Smart India Hackathon, ATL Tinkering Labs exploring IoT agriculture, and hobbyists in IIT, NIT, VIT, or BITS who want hands-on LoRa experience. The intermediate build assumes basic familiarity with Arduino and soldering.
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 talk to the AI companion, which knows the exact wiring, code, and common pitfalls of this kit. You can also message us on WhatsApp for a direct troubleshooting session.
Can this kit measure the nutrient concentration (EC) of my solution?
No, the sensors measure volumetric soil moisture and temperature, not electrical conductivity. For nutrient levels, you would need a separate EC probe. However, consistent moisture and temperature are critical for nutrient absorption, and this kit helps you track them remotely.
How far can the LoRa signal reach?
With the included 433MHz antenna and the RA-02 module, expect 1–2 km in open rural areas. In urban settings with walls, range may be shorter. Line-of-sight placement gives the best results.
Do I need a separate receiver to view the data?
Yes, this kit builds only the transmitting sensor node. To see the data, you need a second Arduino with another LoRa module (not included) connected to a computer or an OLED display. The AI companion includes instructions for setting up a simple receiver circuit.
Hydroponics — Solar-powered Arduino with RA-02 LoRa transmits soil moisture and temperature from a field every 10 minutes.
