1. Introduction

The epConnected Equipment module provides a solution for bringing wireless data collection & management to

industrial settings. The assembly contains a carrier board for the Agora wireless modem board that allows data

acquisition of industrial analog sensors with either 4-20mA outputs or 0-5V ratiometric outputs to be digitized and

sent over the available communication methods on the Agora (Cell, Bluetooth, LoRa). The epConnected Equipment

is intended for use in Class I Division 2 hazardous areas, and voltage sources for the transducer inputs are current-

limited to prevent the possibility of sparking during fault conditions of the field wiring. The board can be configured

to receive power from a universal 120VAC/240VAC source or from a solar panel array. In addition, the device is

provided with a lead acid backup battery. This system is designed to support connection to BLE sensors in Class I

Division 1 hazardous areas.

The epConnected Equipment leverages the capabilities of the Agora module by Embedded Planet. Agora is an

IoT solution platform that incorporates the processing power of an onboard MCU with the wireless connectivity of

cellular, Bluetooth, & LoRa while collecting sensor data. Onboard sensors can include 6-axis IMU, 9-axis IMU, Time-

of-Flight (ToF) distance, temperature/humidity, temperature/humidity/pressure/VOC gas, and sound/microphone.

The cellular module is available in configurations that include GNSS capabilities. Some configurations of Agora

include custom plastics & a LiPo battery with recharging capabilities. Agora can operate as a standalone module or

be integrated into new or existing hardware designs. To learn more about Agora & how to leverage its capabilities,
