Pi Zero W LoRa Remote Sensor Node
Build a 1km+ Remote Environmental Sensor Node with the Pi Zero W and LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Remote environmental data is the backbone of smart agriculture, campus weather networks, and industrial IoT. This kit lets you go beyond breadboard prototypes and build a real field node that collects temperature, humidity, and pressure, then transmits them reliably over more than a kilometre. It’s the exact setup used by engineering teams developing scalable sensor grids.
What You'll Build
You’ll assemble a battery-powered sensor node that uses the Pi Zero W to read the DHT22 and BMP280 sensors. The data is packed and transmitted via the RA-02 LoRa module on the 433 MHz band. Once coded and deployed, your node can sit outdoors, running for days on a single LiPo charge, sending readings to a central Raspberry Pi gateway. You’ll hold a complete, field-ready transmitter that demonstrates long-range IoT communication.
What You'll Learn
- Interface multiple I2C sensors (BMP280) and the one-wire DHT22 with the Raspberry Pi Zero W GPIO.
- Configure SPI communication and libraries for the RA-02 LoRa module, setting parameters like spreading factor and bandwidth.
- Design a reliable power management system using the TP4056 module and 2000mAh LiPo battery with charge and discharge protection.
- Write and flash Python scripts that read sensors, package data, and transmit over LoRa at 1km+ range, including deep-sleep optimisation.

Who This Kit Is For
This kit is tailored for B.Tech ECE and EEE students designing IoT sensor networks for final-year projects or Smart India Hackathon challenges. It’s equally powerful for ATL Tinkering Lab mentors demonstrating long-range communication and for makers prototyping agricultural or industrial monitoring solutions. If you’ve already worked with basic Raspberry Pi and soldering, this project elevates your skill to building deployable wireless hardware.
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 inside the box to launch the AI companion tailored to this kit; it understands every component and connection. You can also reach our support team on WhatsApp for direct assistance.
Do I need two Raspberry Pis to see the sensor data?
This kit builds the transmitter node only. You will need a second Raspberry Pi with a LoRa module (not included) to act as a gateway. The build guide includes the receiver-side Python code ready to run.
Can this node run continuously outdoors?
Yes, the included LiPo battery and TP4056 module create a rechargeable field power system. With the deep-sleep code optimisations taught in the project, the node can operate for days between charges.
Is the soldering difficult for this project?
You will solder the 40-pin GPIO header onto the Pi Zero W and a few passive components. The detailed instructions and AI companion walk you through every joint. It’s a perfect step to master hardware assembly skills.
Pi Zero W reads environment sensors and transmits over RA-02 LoRa to a gateway Pi. 1km+ range.
