The human body proximity sensor is based on the principle of Doppler technology, using a microwave special microprocessor, planar induction 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 impossible to compare the previous alarm circuits composed of infrared, ultrasonic, and pyroelectric elements with conventional microwave circuits. It is described as a good product for security precautions and automatic monitoring. It is very suitable for use in warehouses, shopping malls, museums or financial departments in cooperation with human or object movement detection sensor heads. It has the advantages of concealed installation, large monitoring range and low system cost.
The human body proximity sensor is based on the principle of microwave Doppler, a planar antenna is used as the sensing system, and a type of sensor controlled by a microprocessor. The human body proximity sensor transmits and receives at a microwave frequency of 10.525GHz. The key components of the whole machine are imported components. The design and selection of components ensure the reliability of the product. Using non-contact detection, stable performance and long life, the sensor is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments. Strong anti-radio frequency interference ability and strong penetration ability. Small size, easy to install flexibly.
