DC 12V KK-P25/20 8KG Lifting Solenoid Electromagnet This DC 12V KK-P25/20 8KG Lifting Solenoid Electromagnet consists of an iron core and a coil to attract magnetic substances, using the magnetic action induced by electric current, only while the current is applied. This compact functional device offers high power with high reliability. The structure and design to release the residual magnetism left after de-energization is also one of its unique features. Working Principle: An electromagnet is simply a coil of wire. It is usually wound around an iron core. However, it could be wound around an air core, in which case it is called a solenoid. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.The polarity of the electromagnet is determined by the direction of the current. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -). The direction your thumb is pointing in the direction of the magnetic field so north would come out of the electromagnet in the direction of your thumb. DC electromagnets are principally used to pick up or hold objects. Precaution: Electromagnets must meet the following conditions to achieve maximum suction: The object to be sucked must have good magnetic permeability. Proper use of power supply, rated voltage. The object to be sucked must be flat and clean. The object to be sucked must be greater than or equal to the surface of the magnet( For example the magnet is 20 x 15 mm, so the surface area is S=r²π=10²π mm² so the object to be sucked must be greater than or equal to 10²π mm² ) The object to be sucked must be greater than 5mm. (If the thickness decreases, the suction decreases) The object to be sucked must be close, the middle can’t be interspersed with objects or gaps Suction means more than 5cm in thickness, and surface roughness, the surface is greater than the cross-sectional area of the electromagnet and maximum suction completely fits together on an iron-based material. Electromagnet in working conditions electromagnetic conversion would produce a certain amount of heat, electricity more frequently the higher temperature, which is a normal phenomenon.

Turbidity Sensor With Module for Liquid Particle Detection A turbidity liquid particle detection sensor is a device that is used to measure the turbidity, or cloudiness, of a liquid. Turbidity is often used as an indication of the presence of suspended particles in the liquid, such as dirt, algae, or bacteria. The sensor works by shining a light through the liquid and measuring the amount of light that is scattered or absorbed by the particle detection. Turbidity is the measurement of particulate matter in water. It requires the analog port of the MCU to read the analog value for calculation. It needs turbidity calibration liquid to calibrate. It is not the multimeter that directly measures the voltage. The output voltage of each module is different. The module should be protected from light and light. The temperature and voltage will make the output voltage of the module different.  These decisions are made on the basis of a comparison between clean water measurements (taken at the beginning of the wash cycle) and the wash water turbidity measurement taken at the end of each wash cycle. By measuring the turbidity of the wash water, the dishwasher can conserve energy on lightly soiled loads by only washing as long as necessary. This will result in energy savings for the consumer. Parameters of the Turbidity Particle Sensor: Voltage: 3.3-5V (with anti-reverse circuit) Output: default analog (can set high and low output) Measuring range: 0-1000 NTU Key
