NETVOX R211I is a LoRaWan wireless InfraRED recomte control gateway, it can be used for IR learning and application. After IR learning, R211 can send
the infrared control signal to corresponded electric devices. R211 can receive infrared signal from other infrared device and process predefined action, ex. controlling other LoRa devices.

Principle of Operation

IR spectroscopy (which is short for infrared spectroscopy) deals with the infrared region of the electromagnetic spectrum, i.e. light having a longer wavelength and a lower frequency than visible light.
Infrared Spectroscopy generally refers to the analysis of the interaction of a molecule with infrared light. Netvox LoRa IR Gateway absorbs the IR spectroscopy from remote controller, records code, and emits to IR devices.

Example Applications

Remote controlling of air condition, TV, HiFi Audio, etc.
