Unipi technology currently does not offer LoRaWAN gateways. Note: To use LoRaWAN you need to register the sensor at the public operator or in a database of a private LoRaWAN gateway. Users can create private networks or utilize commercial networks provided by mobile operators. Selected variants also feature wireless communication using the LoRaWAN technology, combining long signal range (up to several kilometers), low energy consumption, and an option of bidirectional communication.
The sensor functions as a Modbus slave, serial line, and TCP parameters can be configured as needed. The second interface is the RS485 standard serial bus for communication via Modbus RTU. Wi-Fi interface supports communication via Modbus TCP, MQTT (including encoded connection support), and REST API. For regular usage, the sensor then switches to Wi-Fi client mode. For initial configuration, the device acts as a Wi-Fi access point. The primary communication interface of indoor air quality sensors is a wireless Wi-Fi connection. Values can be displayed directly in the interface or exported as an Excel file (CSV). A particularly useful feature is the option to store all measured values for up to 7 days. Sensors are provided with a web user interface for displaying measured values and device management including remote firmware updates. In hotel rooms or bedrooms, for example, the LED can be configured to turn off along with the room’s light to prevent sleep disturbance by the LED’s light. Brightness adjustments and on/off switching can be also controlled automatically by a pre-set time schedule or ambient light intensity. Users can also adjust the LED’s brightness or turn it off entirely.
In all models, the LED has a secondary function of indicating wireless communication and device status. For variants lacking the CO 2 functionality, the LED then indicates an air quality index roughly equivalent to CO 2 concentration. For models featuring a CO 2 sensor, the LED indicates carbon dioxide concentration (green = low concentration, red = high concentration). The sensor is also equipped with a multi-colored LED. Note: The power supply and the USB cable are not included in the package and have to be purchased separately. 5 V voltage via a USB power cable with long MicroUSB connector (regular USB cables with short MicroUSB connector cannot be used to power Unipi indoor air quality sensors).24 V⎓/0,5A power supplyconnected to the sensor's terminal block.The sensor features a terminal block for connection of power supply and RS485 bus, and also a MicroUSB power supply connector. The box is designed for easy access to the sensor board itself. The sensor’s circuit board is mounted in a compact design box (IP20 protection) intended for indoor on-wall installation. In addition, selected variants also have an interface for LoRaWAN wireless technology. Due to the RS485 and WiFi interfaces, wide connectivity is ensured. Selected variants are also equipped with a carbon dioxide (CO 2) concentration sensor. Sensors can be used to measure temperature, relative air humidity, barometric pressure, volatile organic compound concentration, and ambient light intensity.
