Compact module that integrates the microwave motion sensor based on the Doppler effect, a signal amplification section (not present in the sensor only), two status LEDs and a trimmer for adjusting the detection distance from 2 to 16 meters. It consists of a transmitting and a receiving section. As soon as the sensor is powered it sends a pulse train with a frequency of 10.525 GHz (low power), when they encounter an object, the pulse train received by the module will be greater or lesser depending on the distance. It can be used for automatic opening of electric doors and gates, automatic switching on of lights, etc. Detection range adjustable from 2 to about 16 meters. When the unit does not detect any presence, the signal assumes a stable value at about 4.2V, while in case of detection, the output signal will go to 0V (square wave). The output is not of the timed type, therefore it will be necessary to couple a timer to it if a load is to be activated automatically, otherwise it can be used only as a detection sensor.
