After testing, the gasoline pressure at idling speed is 260Kpa, and it can reach 310Kpa when ultrasonic wind speed measurement is accelerating, indicating that the oil pressure is normal. Read the data stream, the air mass flow rate at idling speed is 2.2g/s, which is lower than the normal value (2~

Step 1: Parts list·Arduino UNO board·SR04 ultrasonic transducer sensor·USB cable type A/B·Universal 4-pin Grove cableStep 2: Connect the 200KHz ultrasonic transducer to the Arduino development board

basic introduction:Ultrasonic transducers sensor are developed by using the characteristics of ultrasound. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally. Ultrasonic waves ha

Ultrasonic sensors use the vibration of the pressure vibrating ceramics on the sensor head to generate high-frequency (inaudible to human ears) sound waves for induction. If the sound waves hit a certain object and are reflected back, the sensor can receive the echo. The ultrasonic sensor can determ

Foaming agent, also known as styrofoam,which refers to glue with foaming properties and adhesiveness. It is widely used in the filling of window edge joints, expansion joints, and holes. Blowing agents are used in many ways, the most common being used in homes and sometimes in construction. The blow

Augmented reality / virtual reality (AR / VR) systems are being increasingly used in various fields, such as entertainment, education, healthcare, and other industrial applications. With these technologies, users can simulate complex tasks or surgical operations in a virtual space. Sensing technolog

When is faced with thousands of thermistor types, selection may cause considerable difficulties. In this technical article, I will introduce you to some important parameters to keep in mind when is choosing a thermistor, especially when you want to use two commonly used thermistor types for temperat
