Temperature and Humidity Sensor System

Concept

溫溼度是一個環境基礎資訊，當感測環境在於場地較大的地方(雞舍、溫室、農場)，利用有線或是短距離無線裝置(藍芽、WiFi)需要付出大量的成本才能實現。為了實現多點且可以再大範圍中任意移動的特點，利用IOT系統板的無線廣播通訊功能實現遠距離通訊功能。

利用IOT系統板可實現遠距離(2KM)且無線廣播通訊的功能，利用無線廣播機制可以實現接收範圍內，不需要經過裝置配對可以實現多方通訊。

在專案中利用了四塊IOT系統板，其中三塊用於感測與控制，一塊用於人機介面顯示即時資訊且控制特定裝置的輸出功能

Temperature and humidity are basic environmental information. When the sensing environment is located in a large area (chicken coop, greenhouse, farm), using wired or short-distance wireless devices (Bluetooth, WiFi) requires a lot of cost to realize it. In order to realize the characteristics of multi-point and arbitrarily moving in a large range, the wireless broadcast communication function of the IOT system board is used to realize the long-distance communication function.

The use of the IOT system board can realize the function of long-distance (2KM) and wireless broadcast communication, and the use of the wireless broadcast mechanism can achieve within the receiving range, and multi-party communication can be realized without device pairing.

Four IOT system boards are used in the project, three of which are used for sensing and control, and one is used for the human-machine interface to display real-time information and control the output function of specific devices

Data Collectino

廣播通訊功能可以達到多片系統版同時溝通使用，展示中利用三片IOT系統版感測溫溼度並且以無線廣播訊號的方式傳出，其中包含資料編碼與CRC驗證功能

The broadcast communication function can achieve multi-chip system boards to communicate and use at the same time. In the demonstration, three IOT system boards are used to sense temperature and humidity and send them out in the form of wireless broadcast signals, including data encoding and CRC verification functions

The LED in the lower left corner of the video is the indicator light that the signal is received and the CRC verification is passed, and the information on the HMI is updated in real time
