NB-IoT Sensor Uplink Kit - Low-Power Cellular Data Logger Project
NB-IoT Sensor Uplink Kit - Build a Low-Power NB-IoT Cellular Sensor Node with 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.
With this kit, you'll build a self-contained environmental sensor node that transmits temperature, humidity, and atmospheric pressure data over NB-IoT cellular networks - no Wi-Fi or gateway needed. Designed for extremely low power consumption, the node can operate for months on a single small battery, making it ideal for remote agricultural monitoring, smart city deployments, and off-grid data logging where Wi-Fi simply doesn't reach.
What You'll Build
You'll assemble a compact Arduino Nano-based sensor node, powered by a rechargeable 3.7V LiPo battery and managed by a SIM7020 NB-IoT module. The DHT22 and BMP280 sensors capture temperature, humidity, and barometric pressure, while a 0.96-inch OLED displays readings locally. Once programmed, the node automatically connects to a cellular network and pushes sensor data to your cloud platform using MQTT or HTTP - all on a power budget that allows years of unattended field use from a modest battery pack.
What You'll Learn
- Interfacing the SIM7020 NB-IoT module with Arduino via UART and sending AT commands for network registration, data transmission, and deep-sleep modes
- Reading and calibrating DHT22 (temperature / humidity) and BMP280 (pressure) sensors, and combining them into a single data payload
- Implementing power management on Arduino Nano - including sleep modes and efficient sensor wake-up - to extend battery life for months
- Driving a 0.96-inch I�C OLED display to show real-time sensor readings, signal strength, and power status

Who This Kit Is For
CBSE Class 11-12 students exploring IoT and embedded systems, B.Tech ECE/EEE undergraduates working on Smart India Hackathon challenges, and ATL Tinkering Lab mentors needing a reliable NB-IoT sensor prototype will find this kit ready to go. It's also a strong choice for final-year projects at IIT, NIT, VIT, BITS Pilani, and similar institutions where a cellular-connected sensor node demonstrates real-world remote monitoring capability.
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 included QR code to open the AI companion, which walks through wiring, AT commands, and code uploads. For extra help, send a WhatsApp message - our team responds within a few hours.
Do I need a separate SIM card for NB-IoT?
Yes, you'll need an NB-IoT SIM from an Indian provider like BSNL or Jio. Check network coverage in your area before ordering; the SIM7020 module supports Band 8 and Band 5 commonly used in India.
Can I complete this kit without soldering?
Some soldering is required to attach headers and connect the PCB. A basic soldering iron and solder wire are included, and the AI companion guides you through the few joints needed.
Where can I view the sensor data once the node is running?
The SIM7020 sends data directly to cloud platforms via MQTT or HTTP. We provide sample code for Thingspeak, Blynk, and AWS IoT, and the AI companion explains how to configure dashboards for temperature, humidity, and pressure graphs.
SIM7020 NB-IoT module sends sensor data over narrow-band cellular. Very low power 10-year battery life.
