LJ12A3-4-Z/BX NPN DC5-36V 4mm Normally Open Tube Type Inductive Proximity Sensor Switch This LJ12A3-4-Z-BX-NPN DC 5-36V Inductive 4mm NPN-NO Proximity Sensor Switch also known as Approach Sensor is a component widely used in the automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out a control signal. When the metal approaches near-proximity switch sensing area, an Edy Current is induced in metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor. These inductive proximity switches can be non-contact, have no pressure, no spark, and quickly issue the electrical command. Accurately reflect the position and stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments. This 4mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, used for precise positioning of molds, precision machine tools, and robots. Applications: It is widely used in machines, paper making, light industry for limiting stations, orientation taking count, speeding trials, etc. Used in the automatic control industry for detecting, controlling, and noncontact switching.

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 Features: Turbidity can be measured in the range of 0 to 1000 Nephelometric Turbidity Units (NTU). Operates at 3.3-5V and has built-in anti-reverse circuitry for safety. The operating temperature range is from -20°C to 80°C. Uses light scattering or absorption to estimate the presence of suspended particles in liquids. Used in various applications such as water quality monitoring, environmental monitoring, and industrial processes. Turbidity Liquid Particle Detection Sensor Pin Diagram:
