Proximity Sensor is a sensor device used to detect objects approaching or approaching. It can perceive the existence of objects through different principles, such as electromagnetic induction, infrared, ultrasound, etc.

Light Curtain Sensor is a photoelectric sensor used to detect the presence or interference of objects. It consists of a set of transmitters and receivers, which emit a parallel beam of light and use the receiver to receive the beam to detect the presence or interference of the target object.

A measurement sensor is a type of sensor used to measure the position, displacement, or changes in displacement of an object. They are widely used in industries, automation, machinery, construction, healthcare, and other fields. Displacement sensors can provide accurate displacement measurement data for monitoring, control, and feedback systems.

Photoelectric sensors are an efficient and reliable technology that utilizes the principles of optoelectronics for detection and measurement. Photoelectric sensors detect and track targets by sensing the presence, intensity, and position of light. It has advantages such as fast response, high accuracy, and low error rate, and is widely used in industrial automation, robotics technology, safety monitoring, and other fields.

RGB color sensor is a sensor that can detect and measure red, green, and blue light. They provide quantitative data on color by sensing light of different wavelengths and converting it into electrical signals. RGB color sensors are commonly used in various applications, including color recognition, color measurement, etc.
