The EPM2M-AG-BRD-CELL is a flexible multi-sensor module designed to be used as an assembly for an OEM to add to a system or as a complete solution for monitoring. Cellular connectivity allows the epSensor to be used in locations without Ethernet or Wi-Fi access. Sensors allow for air quality monitoring, temperature / humidity, motion detection, audio detection, light sensing, accelerometer and time of flight.

An expansion port allows for additional custom designed sensors to be integrated into the design for other application needs.
