Used in conjunction with ITS 3G or 4G or LoRa® and Zigbee endpoints, the EM C104 is an Internet of Things (IoT) extension designed to extend 4-20 mA current sensing capabilities.

Its applications are numerous, from large industrial parks to challenging smart city projects. With the possibility of measurements ranging from tank temperature, oil pump pressure and CO2 levels – information that is collected and sent to cloud application.

Features

Up to 4 current sensors, 4–20mA

This extension module provides the Khomp IoT Endpoints with the capacity to measure the most commonly used electric currents across industries (4–20mA), making it possible to monitor the correct operation of devices, which inform their maintenance data by means of current variations.

• It has 4 analog input ports to connect the current outputs (4–20mA)
• It has a 4-channel AD/I2C converter chip to read analog inputs and convert them to data in order to send them via I2C to the Khomp IoT Endpoints
• It is compatible with LoRa®, Zigbee, ITS 402 Endpoints
• Indoor plastic case for connection to Khomp IoT Endpoints
• It has a 12 VDC power input

Application Model

Connected to an urban structure, the sensor detects the amount of CO2 present in the air and sends the data through the extension.

With the extensor integrated to the sensor inside the float, it is possible to measure the pH of the water in that region.

In conjunction with the NIT LoRa endpoint, the extension can monitor the water level of the reservoir and water tank.
