Based on proprietary Plug & Play RF networking protocol for simple network configuration.
Key features
LoRa is a low-power wireless platform and a core technology underpinning the Internet of Things (IoT). Boasts wide-area coverage and high signal penetration:
- Up to 2 km in open areas
- Up to 1 km in urban areas
UNITESS AMBIENT radio-frequency USB receiver is a short-range device (SRD), which reads the data from thermo hygrometers.
This wireless USB receiver leverages industrial, scientific, and medical (ISM) radio bands. Such portions of the radio spectrum can be used for any purpose and without a license.
USB receiver is used to:
- Receive the RF channel information from THB1 thermo hygrometers (almost unlimited quantity);
- Transfer information to a PC via USB;
- Transmit control and setting commands to thermo hygrometers.
The product can only work in the mode of receiving information.
