Lawn Irrigation Controller Kit
Build a Precision Lawn Irrigation System with ESP32 and LoRa Nodes
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take the guesswork out of lawn care by deploying a network of wireless sensor nodes that measure soil moisture, temperature, humidity, and barometric pressure across your field. This kit guides you through building a resilient LoRa mesh that talks to an ESP32 gateway, streaming real-time environmental data to the cloud via Wi-Fi—so you always know exactly when and where to water.
What You'll Build
You'll assemble and program four battery-powered remote sensor nodes, each equipped with a DHT22, BMP280, and capacitive soil moisture sensor. A central ESP32 gateway aggregates LoRa transmissions from up to 1 km away and pushes the formatted data to a cloud dashboard. The complete system delivers a field-level view of micro-climates, enabling data-driven irrigation scheduling that reduces water waste.
What You'll Learn
- Design and deploy a star-topology LoRa sensor network with addressing and packet routing
- Interface multiple I2C sensors (DHT22, BMP280) with Arduino Nano and handle data fusion
- Configure an ESP32 as a dual-radio gateway (LoRa + Wi-Fi) for cloud telemetry
- Implement power-optimized deep-sleep modes for battery-operated remote nodes

Who This Kit Is For
Agri-tech enthusiasts, B.Tech ECE/EEE students building IoT agriculture capstone projects, Smart India Hackathon teams prototyping smart farming solutions, and farm owners who want to implement precision irrigation for lawns, nurseries, or smallholdings. If you have basic Arduino experience and want to master long-range sensor networks, this kit is your next 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, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access your AI build companion trained on this exact project, or message us on WhatsApp for engineer support within 2 hours.
How far can the LoRa nodes communicate?
In open field conditions, the RA-02 SX1278 modules can reliably transmit over 1 kilometre. The kit includes tuned 433MHz antennas to maximise range.
Which cloud platform does the gateway upload to?
The example firmware sends data to ThingSpeak by default, but the AI companion provides guidance for Blynk, Adafruit IO, or a custom MQTT broker—you decide.
Can I expand the network later?
Absolutely. The LoRa addressing scheme supports up to 254 nodes. Additional sensors and ESP32 boards can be added with the same firmware logic, and the AI companion can help you scale.
Lawn — Four LoRa nodes spread across a field send micro-climate data to a gateway ESP32 which uploads to cloud.
