Application of Hall Element on Smart Toilet

Smart toilets are mainly used in the medical and geriatric health care industries. With the improvement of people's living quality and production technology, smart toilets have been gradually improved from the original warm water wash function to the current toilet seat cover and warm water wash , Warm air drying, sterilization and other functions of the smart toilet. So smart toilets are now more and more commonly used in home life.

Smart toilets have 2 parts depending on the function that will be used for the Hall element, one part being a flush part and one part being a water flow control part.

Intelligent toilet water flow control is relatively simple, the magnet embedded in the turbine blades, the water flow through the blades when the blades on the magnet rotation, Hall according to the detected signal sent to the magnetic field control system to calculate the amount of traffic. Intelligent toilet water flow calculation components. Their characteristics of high frequency, small size, good stability, the use of intelligent toilet is ideal.

The simplest toilet flushing function, the key element is Hall. Hall installed in the brushless DC motor, the motor speed to detect, so as to control the rotation of the nozzle to achieve the goal of flushing. The principle is that when Hall detects the motor speed reaches the set number of times, the feedback signal to the control system, turn off the solenoid valve, stop flushing, to complete the flushing.

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
