Indoor air quality sensor | Unipi

The second interface is the RS485 standard serial bus for communication via Modbus RTU. The sensor functions as a Modbus slave, serial line and TCP parameters can be configured as needed. Selected variants also feature wireless communication using the LoRaWAN technology, combining long signal range (up to several kilometres), low energy consumption and an option of bidirectional communication.
