In the modern day where sensor technology is becoming more and more mature, due to the increase in the accuracy and precision of its measurement functions and measurement parameters, and the reliability of sensors has gradually improved, sensors are currently being used in a large number in industrial and automotive manufacturing With these sensors, the detection and control system of the automotive industry has taken to a new level.
The temperature sensor is mainly responsible for several areas. One is the sensor that detects the temperature of the engine. The engine is the heart of a car. Its normal work can drive the entire car to move. The second is the temperature sensor used for water temperature and oil temperature measurement. Check the water and oil temperature in the water tank and the oil tank. The third is the temperature sensor inside and outside the car, which is used to detect the temperature of the air outlet and the temperature inside and outside the car.
The pressure sensors mainly include a tire pressure detection sensor, an oil pressure sensor, and an intake pressure sensor. As the name suggests, the tire pressure detection sensor is a sensor used to monitor the tire pressure. It displays the detected data in the control system to let the driver know whether the current tire is under-inflated to reduce accidents caused by tire cracks. Oil pressure sensor It is used to monitor whether the car oil pressure is normal. If it is abnormal, the indicator light on the dashboard will prompt the driver to check whether the oil is sufficient. The intake pressure sensor is used to detect the pressure of the intake manifold. It is based on the engine speed and The load detects the pressure in the manifold, and then converts the detection signal into a voltage signal and sends it to the electronic control unit (ECU). The ECU controls the amount of fuel injection based on the magnitude of the voltage signal.
The oxygen sensor is used to detect the oxygen content concentration in the exhaust gas, and it provides this data to the electronic control unit (ECU), and then the ECU will determine the combustion status of the engine or the operation of the catalyst through the oxygen content concentration signal provided by the oxygen sensor effectiveness.
The liquid level sensor is a sensor used to detect the liquid volume in the water tank and the mailbox. The data it detects will also be displayed on the instrument panel, which is used to remind the driver of the water and oil capacity at this time.
Of course, the sensors used in cars are much more than that. There are dozens of sensors used in a good car. Most of the sensors used in cars are small size, small quality, low power consumption, high reliability, high sensitivity, high resolution. Mainly digital. Xinxin Electronics is committed to contributing to highly sophisticated sensors.
