Private LTE CAT-M1 IoT Node — Build a Battery-Powered Cellular Sensor Station with SIM7080G & Arduino Nano

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

Deploy a standalone sensor node that reports temperature, humidity, pressure, and timestamped data over private LTE CAT-M1 — without WiFi, without gateways. This kit equips you with a SIM7080G module, Arduino Nano, and precision sensors to create a field-ready logger that sleeps for years on a single coin cell using PSM. Perfect for remote agriculture monitoring, industrial asset tracking, or Smart India Hackathon challenges requiring long-life cellular connectivity.

What You'll Build

You'll assemble and program a weatherproof IoT node that wakes up periodically, reads DHT22 and BMP280 environmental data, logs it to microSD with an RTC timestamp, displays status on an OLED, and transmits everything over LTE CAT-M1 using ultra-low-power PSM mode. The firmware optimises battery drain so the node can run unattended for months on the included LiPo, mimicking a 2-year coin cell deployment once fine-tuned.

What You'll Learn

• Configure and drive the SIM7080G CAT-M1 module from Arduino using AT commands and TinyGSM library
• Implement Power Saving Mode (PSM) to reduce cellular modem current draw to microamps between transmissions
• Interface multiple I2C sensors (DHT22, BMP280, DS3231) on a shared bus and log to SD card with FAT32
• Design a bare-metal soldered assembly on protoboard and encapsulate it in an IP65 enclosure for field deployment
