The Agora EPM2M-AG-CELL epSensor is a flexible multi-sensor device designed to be used as a module by OEMs to be added to a system or as a complete solution for monitoring air quality, temperature/humidity, motion detection, audio detection, light sensing, accelerometer and time of flight. Cellular connectivity allows the epSensor to be used in locations without Ethernet or Wi-Fi access. epSensor enables OEMs to easily add automated asset tracking and replenishment features to their equipment while also benefitting from rich datasets that can be used for machine learning techniques to gain better insights in to usage and operations.

  • Mbed has developed universal communication drivers for supported MCUs, abstracts useful network interfaces and speeds up development in general.
  • Mbed solved the challenges of inter-IC communication and compiling.
  • The Mbed compiler and interface abstractions circumvent the effort of learning each manufacturer’s HAL and/or SDK for programming a new part. By simply changing the target flag in the compiler it is possible to run the same code on multiple targets.
  • The product took 6 months to develop between 3 software engineers and 2 hardware engineers.
  • Specification
