ESP32 LoRa Indoor Plant Monitor Kit
Build an 8-Zone Variable Rate Irrigation System with ESP32 + LoRa for Precise Indoor Plant Care
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You're not just monitoring a single potted plant. With eight wireless sensor nodes spread across a grow room, greenhouse, or indoor farm, this kit maps soil moisture and temperature heterogeneity in real time - enabling variable rate irrigation that optimises water use and plant health. No more guesswork, no more uniform watering that leaves some plants overwatered and others thirsty.
What You'll Build
A wireless sensor network that measures soil moisture and temperature at eight locations simultaneously. Each node, built around an Arduino Nano and Lo-Ra RA-02 module, transmits data to a central ESP32 gateway. The gateway processes the data, visualizes it on an onboard display or pushes it to a cloud dashboard, and can control irrigation valves to deliver water precisely where needed based on measured variability. You'll have a working IoT system that transforms how you irrigate your indoor plants.
What You'll Learn
- Design and deploy a LoRa mesh network for reliable indoor long-range communication
- Interface capacitive soil moisture sensors and DS18B20 temperature probes with Arduino
- Program an ESP32 as a central data aggregator and web dashboard server
- Implement variable rate irrigation logic based on real-time sensor thresholds

Who This Kit Is For
Advanced makers, agritech engineering students (B.Tech Agri, ECE), and researchers working on precision irrigation. It's ideal for Smart India Hackathon projects focused on water conservation, ATL Tinkering Labs mentors designing controlled-environment agriculture experiments, and indoor farm operators in cities like Bengaluru and Hyderabad who need to scale plant monitoring cost-effectively.
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?
Our AI companion, accessible via the QR code on the box, can walk you through every wiring and code step. If you need a human second opinion, WhatsApp support is included.
Can this kit scale to more than eight nodes?
The LoRa network can support additional nodes with minor code modifications, but the included components are optimised for an eight-node setup. We provide guidance to expand up to 32 nodes using the same gateway architecture.
Does this work outdoors or in a large field?
The kit is designed for indoor environments, but the waterproof enclosures protect against splashes. For outdoor field deployment, you may need higher-gain antennas and weatherproof enclosures, which we can recommend.
What coding experience is required?
You'll program both Arduino Nano nodes and the ESP32 gateway. Basic C/C++ skills are needed; our AI companion provides full code and explains each section, so motivated beginners can follow along with guidance.
