汽車引擎冷卻液溫度感知器

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?

透過將 DS18B20 數位感測器連接到 Arduino 來建構一個簡單的電路

DS18B20 數位溫度感測器連接 Arduino

Today I will show you how to use the DS18B20 digital temperature sensor with an Arduino so you can measure the temperature of air, liquids such as water, and the ground.
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.
