What is a human proximity sensor

The human body proximity sensor is based on the principle of Doppler technology, using a microwave dedicated microprocessor, a planar sensor antenna, and imported components. It not only has high detection sensitivity, wide detection range, but also works very reliably. Generally, there is no false alarm, and it can be -15 It works stably in the temperature range of ~+60 degrees. It is unmatched by the previous alarm circuits composed of infrared, ultrasonic, and pyroelectric components and conventional microwave circuits. It is currently the best product for safety precautions and automatic monitoring.

The human body proximity sensor is also called a non-contact proximity sensor, which is an ideal electronic switch sensor. When the metal detector is close to the sensing area of ​​the sensor from a long distance, the switch can quickly issue electrical commands without contact, pressure, sparks, and accurately reflect the position and stroke of the motion mechanism. Even if it is used for general stroke control, its positioning accuracy , Operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments are incomparable to general mechanical limit switches. It is widely used in machine tool, metallurgy, chemical, textile and printing industries. In the automatic control system, it can be used as a limit, counting, positioning control and automatic protection link. The proximity sensor has the characteristics of long service life, reliable operation, high repeat positioning accuracy, no mechanical wear, no spark, no noise, and strong anti-vibration ability. Therefore, so far, the application range of proximity sensors has become wider and wider, and the speed of its own development and innovation is also extremely rapid.

The human body proximity sensor has been gradually recognized and applied as a technical defense method. In order to better implement the national standard of GB/T10488-1997 human proximity sensor, and enable more people to understand the principle and application of human proximity sensor, we now introduce the human proximity sensor developed and produced by Nanjing Yuantuo Technology. Basic knowledge of sensor principles and applications.

The application of human proximity sensor in ATM teller machine monitoring:

ATM dedicated human proximity sensor YTMW8631 and human activity monitor YT-EWS, a control device used to detect human proximity, can accurately detect the proximity of nearby people, and are currently the best choice for alarm and status detection. The sensing part has a high detection sensitivity to the movement of the accessory person, and suppresses the sound signal of the surrounding environment. It has a strong anti-interference ability. It can be widely used in anti-theft devices in ATM, insurance and other occasions. It is easy to install and can be level. Or installed vertically. The sensitivity of human body induction is continuously adjustable, which makes the human body proximity sensor suitable for many different occasions.

It is widely used in financial industry and commerce, self-service banking, ATM monitoring human body approaching alarm, etc. The internal use of microcircuit chip for program control processing, with high detection sensitivity and trigger reliability detection and control two parts into one, low standby power consumption, switch signal output, directly trigger alarm recording, easy to use.
