Hall Effect Sensor Design Tips

图片
As part of the automotive industry,  Hall Effect Sensor  are used to detect end positions or measure linear or angular motion in a wide range of applications such as chassis, safety, body, power and power transmission. At present, an important topic in the research and development of leading automotive industry is functional safety. Functional safety affects the design and functional settings of all application system components, including Hall sensors. Due to the non-contact measurement principle and high reliability of  Linear Hall Sensor , sensing solutions implemented with Hall sensors have become the first choice in many applications. In order to achieve ever-increasing safety and reliability characteristics, the highest precision of the switching threshold becomes the basic parameter of the  Latch Hall Switch IC  specification. There are two sources of jitter in the Hall switch. First, the thermal noise of the Hall plate and the threshold noise caused by signal processing;

The Process Technology Of Hall Effect Sensor

In order to accurately distinguish the cause of  Hall Effect Sensor  abrupt signal generation, a wavelet band analysis method based on mathematical model is proposed. For the measurement and control system in industrial process, the relationship between the frequency composition of the output mutation signal and the cause of the mutation is analyzed. Using wavelet band analysis technology, the high and low frequency signals are separated, and energy statistics are performed. According to the change of the energy ratio of high and low frequency signals, the cause of the mutation signal is judged. The computer simulation of the classic control system and the experimental results of the constant pressure water supply system show that the method can effectively diagnose whether the  Magnetic Sensor  is faulty. In the measurement and control system, the output signal of the sensor is affected by many factors, and often abrupt changes. These mutation point values contain important fault i

What Is The Magnetic Switch?

A  Magnetic Switch  is exactly like a light switch: it functions out a circuit on or off based on what place the arm of this change is in. The sole distinction is that a magnetic switch is run by means of a magnet, instead of your fingers. A magnetic switch includes an arm of metal that's fixed on one end, two switch connections which are near the free end of the arm, along with a movable magnet. Some also have two straps.  AH Electronic features electromechanical reed touch magnetic buttons and digital versions which function in line with the Hall along with magnetoresistive principle.  With our extensive selection of  switches, Hall/  Wiegand Sensor  and so on, we provide our clients powerful and flexible solutions. We are a leading  Hall Sensor Suppliers  in China. The products we provide can meet any of your requirements.

Application Of Hall Switch In Sweeping Robot

The Hall element mainly plays a role in controlling the switch in the sweeping robot, and the Unipolar and the  Bipolar Hall IC  are the most widely used. According to the need, the Hall sensor will be installed in the switch part of the fuselage, and will run the "start" or "stop" command after receiving the command. Since the sweeping robot operates on a rechargeable battery, it is more stringent in power consumption requirements, and often uses Bipolar low-power  Hall Switch  such as YS4913, YS4915, YS248, etc.; if the power consumption is not very high, You can use the unipolar Hall for design. The induction mode of the  Unipolar Hall Switch IC  and the holistic Hall is similar. When the magnet is close, the Hall outputs a low level. When the magnet leaves the Hall output high level The only difference is that the unipolar Hall needs to specify the magnetic pole to work. The omnipolar Hall can sense the operation regardless of the NS.
