Build Your Own Private 4G LTE Router Node with Raspberry Pi Zero 2W & IoT Sensors

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform a Raspberry Pi Zero 2W and SIM7600 module into a self-contained 4G LTE router that bridges a local Wi‑Fi sensor network to the internet. Three battery‑friendly ESP32 boards read DHT22 temperature and humidity data at remote locations—think off‑grid agricultural monitoring, construction site sensing, or a campus‑scale weather mesh. This kit gives you every chip, antenna, and wire to build the architecture in a single focused sprint.

What You'll Build

A compact LTE gateway that runs its own Wi‑Fi hotspot, MQTT broker, and dashboard. Three ESP32‑powered sensor nodes publish real‑time climate readings from across your site. The Raspberry Pi logs everything locally, pushes data to cloud services if you choose, and remains accessible via private LTE even where broadband doesn't reach. You’ll end with a deployable networking stack, not a breadboard demo.

What You'll Learn

• Configure PPP and wvdial for the SIM7600 4G LTE shield on Raspberry Pi OS Lite
• Set up hostapd and dnsmasq to create a private Wi‑Fi access point with DHCP
• Program ESP32 boards to read DHT22 sensors and transmit via MQTT over local Wi‑Fi
• Integrate Mosquitto MQTT broker, Node‑RED, and a real‑time dashboard on the Pi gateway

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Advanced engineering students and makers prototyping private LTE backhauls for IoT sensor networks. It fits final‑year B.Tech ECE/EEE projects, Smart India Hackathon teams tackling rural connectivity, and R&D labs at IIT, NIT, or VIT that need a repeatable edge gateway. ATL mentors moving beyond introductory kits will find a complete, scriptable foundation for environmental monitoring.

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.
