Product Highlights and Programming Support
2.1 Design Philosophy
The EC-M12 is purpose-built as a battery-powered cellular IoT data logger optimized for industrial reliability, environmental endurance, and ease of deployment. It operates seamlessly in applications that require years of maintenance-free data collection and transmission.
2.2 Programming and Software Support
Developers can program the EC-M12 using the Arduino IDE, supported by open-source libraries and sample projects. NORVI provides reference codes on GitHub, including:
- A testing program that covers most hardware functionalities (excluding cellular connectivity);
- A data transmission program capable of reading analog sensor data and uploading it to the Datacake IoT platform over LTE-M or NB-IoT.
This flexibility allows engineers to quickly prototype and integrate the EC-M12 into custom industrial automation systems or environmental monitoring networks.
2.3 Target Applications
The EC-M12 is designed for long-term industrial and environmental monitoring use cases, such as:
- Water level and tank monitoring
- Pressure and flow measurement in pipelines
- Data acquisition from remote sensors via RS485
- SCADA (Supervisory Control and Data Acquisition) system integration
Its low-power architecture and cellular communication capabilities make it suitable for standalone operation in locations without grid power or wired communication infrastructure.
Among existing cellular-based industrial data loggers, the Inventia MT-718 PS is one of the closest alternatives to NORVI’s EC-M12. The table below highlights the key differences:
| Comparison Aspect | NORVI EC-M12 | Inventia MT-718 PS |
|---|---|---|
| Protection Rating | IP67 | IP68 (higher water resistance) |
| Modem | SIM7070 | SIMCom A7672E / SIM7070G |
| Storage | microSD slot (up to 128 GB) | 8 GB / 16 GB internal flash memory |
| I/O Interfaces | 2× 4–20 mA inputs, 1× RS485 (optional) | RS485 and multiple I/O interfaces |
| Power Options | Battery power or 5 V USB (for debug) | 3–8 V DC input or battery operation |
| Main Advantage | Compact form factor and cost efficiency | Extended features and broader I/O compatibility |
The NORVI EC-M12 prioritizes energy efficiency and affordability, whereas the Inventia MT-718 PS provides higher ingress protection and broader I/O flexibility at a larger size and cost.
As of the latest update, the NORVI EC-M12-BC-C6-C-A NB-IoT/LTE-M Industrial Data Logger is priced at approximately USD 94 through NORVI’s official online store.
