What is the Method of using Hall to Detect Speed?

As a Micropower Omnipolar Hall Sensor Supplier, share with you. The magnet is fixed on a turntable, and the turntable is connected to the motor shaft to rotate synchronously (this is just the principle, you can set it to rotate or slide according to your needs).
When the magnet passes through the Hall sensor, Hall will record and generate a corresponding pulse. We can calculate the measured speed by calculating the interval between two consecutive pulses.

Hall IC can also be used in electronic blood pressure meters
Blood pressure measurement is generally divided into two types, one is the traditional auscultation method, and the other is the oscillometric method, that is, the oscillation method, which is used in electronic blood pressure measuring instruments. Electronic sphygmomanometer is a medical device that uses modern electronic technology and the principle of indirect measurement of blood pressure to measure blood pressure. With the improvement of people's self-health awareness, the electronic sphygmomanometer has become the main tool for home self-testing blood pressure.
The electronic blood pressure meter is composed of a cuff, a measurement system, and a display panel. In order to avoid the phenomenon of inaccurate measurement results due to human leaks, Hall sensors are often installed in the main body of the measuring instrument for position monitoring. Hall mainly plays the role of position detection in the electronic sphygmomanometer.
During the measurement process, the air sleeve needs to be fixed at a certain position on the arm, the air tube is connected to the measuring instrument, the booster pump inflates through the air tube, and the blood pressure meter starts to work. A small magnet is fixed in the gas pipe plug part, and a Hall sensor is installed at the position of the docking socket of the blood pressure meter, so that it can be well monitored whether the gas pipe is inserted in place, and whether the booster pump can normally deliver gas. When the Hall sensor detects the air leak, it will send a signal to the host of the blood pressure meter. At this time, the electronic sphygmomanometer will send an alarm signal, so that the person who measures it can adjust it in time.
All-pole halls are often used in electronic blood pressure measuring instruments. They are small in size and easy to hide and install. Higher sensitivity can provide accurate and stable magnetic switch points. The power consumption is extremely low to meet the battery power supply. The response speed is also very high. Fast, very suitable for use in electronic blood pressure meters.

Omnipolar Hall IC

图片
  Omnipolar Hall IC The omnipolar Hall-effect sensor  includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open-drain output driver, etc. Produced with CMOS technology, an omnipolar Hall IC is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). More detail of China Hall Sensor , please via: https://www.ahest.net/

Method Of Detecting Switch Type Hall Sensor

图片
In the use of hall sensor for maintenance machinery, we will encounter holzer not working, from holzer's shape can not distinguish whether the holzer element is damaged, and how to detect whether the switch type of hall sensor is damaged. Taking Holzer YS282 as an example, the test method of switch type Holzer element is as follows: First, find a resistance R of 1K Omega, which is connected to the figure 1 and 3 feet, and connect the positive pole of the DC power of the 12V to the foot of the  switch type hall sensor YS282, and the anode is connected to the foot. The multimeter is placed in a DC 50V file, the red pen is connected to the foot, and the black pen is connected to the foot, and the pointer changes of the multimeter are observed. When the magnet N is very close to the test point of the hall sensor YS282, the pointer of the multimeter is deflected from the high level to the low level; when the N pole of the magnet is far away from the test point of the Holzer element Y

How To Use Water Flow Sensor？

图片
The  Water Flow Sensor  consists of a plastic valve body, a water rotor and a Hall Effect Sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This type of sensor can be found on different diameters, water pressure (MPa) and flow rate (L/m) ranges. Make sure to select one that will cover your needs. The sensor that I have it has 20mm diameter, <1.75Mpa water pressure and ~30 L/m flow rate range. A  Water Flow Meter Sensor  is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.  Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall cost-of-ownership. The question is: What water flow meter should you choose for your w
