Car Engine Coolant Water Temperature Sensor
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 temperature sensor connected to MCU
DS18B20 je pogosto uporabljen digitalni temperaturni senzor. It outputs digital signals, has the characteristics of small size, nizki stroški strojne opreme, Močna sposobnost proti interferenci, visoka natančnost, and is widely used.
Design of DS18B20 Digital Temperature Sensor for STM32
DS18B20 is a digital temperature sensor that uses a single bus timing to communicate with the host. Only 1 Wire is needed to complete the temperature data reading;
DS18B20 has a built-in 64-bit product serial number for easy identification. Multiple DS18B20 sensors can be connected to 1 Žica, and through 64-bit identity authentication, the temperature information collected from different sensors can be read separately.

Rešitev vezja za zajem temperature PT100/PT1000
Kovinski toplotni upori, kot je nikelj, Baker in platinasti upori imajo pozitivno povezavo s spremembo odpornosti s temperaturo. Platina ima najstabilnejše fizikalne in kemijske lastnosti in se najpogosteje uporablja. Obseg temperature najpogosteje uporabljenega platinskega upora PT100 je -200 ~ 850 ℃. Poleg tega, Območje merjenja temperature PT500, Pt1000, itd. se zaporedno zmanjšujejo. Pt1000, Območje merjenja temperature -200 ~ 420 ℃. V skladu z mednarodnim standardom IEC751, temperaturne značilnosti platinastega upora Pt1000 izpolnjujejo naslednje zahteve:
