Commonly used NTC thermistors for air conditioner
There are three types: indoor ambient temperature NTC, indoor coil NTC, and outdoor coil NTC. Higher-end air conditioners also use external ambient temperature NTC, compressor suction and exhaust NTC, ETC.
How does the car reflect the temperature of the car engine coolant? It is through the water temperature sensor, which is also called the water temperature sensor plug. So where is the specific location of the car water temperature sensor? The water temperature sensor enables the control unit to identify engine overheating or an unusual rise in temperature. How much does a car water temperature sensor cost?
DS18B20是數位溫度感測器，使用單一匯流排時序與主機通訊. 僅有的 1 需要接線才能完成溫度資料讀取;
DS18B20內建64位元產品序號，方便辨識. 可連接多個 DS18B20 感測器 1 金屬絲, 並通過64位身份認證, 可以分別讀取不同感測器採集的溫度訊息.
今天我將向您展示如何使用 DS18B20 數位溫度感測器和 Arduino 來測量空氣溫度, 水等液體, 和地面.
將 DS18B20 數位溫度感測器連接到 Arduino, 你需要執行以下步驟:
硬體連接:
將DS18B20的VCC接腳連接到Arduino的3.3V電源腳.
將DS18B20的GND接腳連接到Arduino的接地腳.
將DS18B20的資料接腳連接到Arduino的GPIO接腳 (例如, GPIO4).
在資料接腳和3.3V電源接腳之間連接4.7kΩ上拉電阻.
高精度、精密NTC熱敏電阻感測器應用於各行業, 從醫療到工業應用. 醫療產業在包括導管在內的各種應用中依賴 NTC, 透析設備, 和病患監護. 此醫療感測器部件是 1355 37°C 時的歐姆 Beta 值 25/85 的 3976.
