LoRa Products
LoRa (Long Range) is a wireless technology which can provide long range, low power consumption devices for Internet of Things (IoT) networks.
LoRa 設備和開放的LoRaWAN® 協定支援智慧物聯網應用，可以解決一些問題：電源/能源管理、自然資源監測、污染控制/監測、災害預防等。我們採用LoRa 技術，為以下領域提供私有LoRa 平台產品：我們的顧客。
Why LoRa?
LoRa is a long range and low power consumption wireless technology designed for unlicenced bands: 433, 868 and 915 MHz. LoRa products can be designed based on open LoRaWAN protocol for private networks, the major equipment consist of (1) End Point devices – Sensors/controllers, (2) Gateway, and (3) Server for bi-directional data communications.
LoRa 提供了一種替代方法來補充 (1) 建築物內的有線 RS-485 網路和 (2) WiFi 覆蓋範圍不足的問題。 主要優點是 LoRa 技術大大減少了佈線規模。 安裝變得容易，節省人力，同時維護也變得簡單。
Anneal LoRa Products
Anneal designed the Private LoRa Network products based on simplifying the open LoRaWAN architecture. Our products consist of (1) Sensors/Activators, (2) LoRa Gateway, (3) Server and optionally (4) LoRa Repeater. The sensors consist of (1) Air Quality monitor – PM1.0/2.5/10, CO, CO2, TVOC, HCHO, O3, LPG, H2, etc., (2) Power/Energy monitor – measure single phase and 3-phase voltage, current, watt, wattHour and phase factor, (3) Temperature/Humidity, Water Tank Depth, Water leakage, (4) Digital Input (DI) and Analog Input (AI). The activators consist of Digital Output (DO) and Analog Output (AO).
Data from sensors are received by the LoRa Gatewat, and Data for activators are relayed by the LoRa Gateway. LoRa Repeater is use to extend the range of sensors/activators. Server accumulates data from LoRa Gateway and Analyze the data.
