Infrared Repeater

Replace Infrared Controls and monitor Temperature/Humidity.


The Infrared Repeater, or NIR 21IR, is an endpoint in the Khomp IoT line that was designed for automation of infrared devices in indoor environments. Using IEEE communication, 802.15.4 (Zigbee), the device is able to capture and store commands, making it an intelligent option for replacing common remote controls.

This substitution, for example, automates the management of equipment, such as air conditioning, creating more practical and sustainable routines.

The architecture of the NIR 21IR also includes a temperature/humidity sensor that allows for monitoring in real time and can be equipped with up to four 1-wire probes to measure additional points or nearby environments

Another interesting feature is the ability to integrate the NIR 21IR into the IR Extender, an accessory that blocks the signals of other devices/commands to prevent fraud and guarantee total control of monitored equipment.
