ESP32 LoRa Houseplant Monitor Kit: Wirelessly Track All Your Plants
ESP32 LoRa Houseplant Monitor Kit: Wirelessly Track Every Plant in Your Home
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine glancing at your phone and instantly knowing which houseplant needs water, which is too cold near the window, and which is thriving in the humid bathroom corner-all without walking from room to room. This kit lets you build exactly that: a scalable indoor plant sensor network. Four battery-powered Arduino Nano sensor nodes measure soil moisture, air temperature, humidity, and barometric pressure near your plants. They send readings over LoRa to an ESP32 gateway, which uploads everything to a cloud dashboard you can access from anywhere.
What You'll Build
You'll assemble and deploy five intelligent modules-four sensor nodes and one gateway-that form a private long-range wireless mesh for your home. The gateway shows live data on a local screen and pushes it to the cloud every ten minutes. You'll set up custom thresholds so the dashboard sends a notification when soil dries out or a room drops below 15 �C, protecting your ferns, orchids, and fiddle-leaf figs without guesswork.
What You'll Learn
- Configure SX1278 LoRa modules for reliable point-to-multipoint communication indoors across walls
- Program Arduino Nano nodes to sleep between readings, extending 18650 battery life to weeks
- Set up an ESP32 as a dual-role gateway: local data display and HTTP/MQTT cloud upload over Wi-Fi
- Calibrate capacitive soil moisture sensors and DHT22/BMP280 for consistent, accurate plant-zone data

Who This Kit Is For
Designed for advanced hobbyists, B.Tech ECE/EEE students working on IoT capstone projects, and professionals prototyping precision agriculture or smart-greenhouse solutions. If you've already built Arduino projects and want to dive into real-world LoRa mesh networking with cloud integration, this kit gives you the hardware and guided build to make it work. Perfect for teams participating in the Smart India Hackathon or individuals at IIT/NIT/VIT/BITS who need a reliable plant-monitoring prototype ready to present.
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?
The AI companion walks you through each soldering and programming step with photos and code snippets. For trickier LoRa tuning issues, just message us on WhatsApp and we'll help you adjust spreading factor and bandwidth in under an hour.
Can I expand the network to more plants later?
Yes. The LoRa star topology easily scales to ten or more nodes with the same gateway. Additional Arduino Nano + RA-02 pairs can be ordered individually from our store and swapped in with a one-line ID change in the code.
Does the cloud dashboard work with my existing Wi-Fi at home?
Absolutely. The ESP32 gateway connects to any 2.4 GHz Wi-Fi network and pushes data to ThingSpeak or a custom MQTT broker. The AI companion helps you configure the endpoint during the build, and you can view live charts on any browser.
How long do the 18650 batteries last in the sensor nodes?
With the deep-sleep intervals included in our code, a single 18650 cell powers a node for three to four weeks of continuous soil moisture, temperature, and humidity logging before needing a recharge.
Houseplant - Four LoRa nodes spread across a field send micro-climate data to a gateway ESP32 which uploads to cloud.
