Microwave speed and distance sensor
Detect motion using radio frequency. Compared to traditional infrared PIR sensor, able to penetrate opaque non-conducting object. Widely used in all kinds of human body induction lighting and anti-theft alarm, etc.
Feature: high sensitivity, Long distance detection, high reliability, detection angle is large.
Detection range is about 20 meter.
Note : 1. The detection range depends on the reflectance and size of the target and the signal to noise ratio.
Doppler speed at 2.10.525 GHz is 31 Hz/mph
3. The module must be mounted so that the antenna surface (the side of the non-aluminum shield is the antenna surface) faces the detected area, and the user can adjust the direction to achieve the best coverage.
Input supply : 5V
current consumption : 30mA
Output : Analog, frequency for speed and amplitude for distance
IF output : when an object at HB100 to the effective detection range 1M / S velocity relative to antenna face, the IF output terminal will output 72Hz / s , the pulsating output frequency of IF is approximately linear with the relative radial movement speed of the object. IF magnitude output amplitude of the object, related to the distance, when a weight of 70kg , height 170cm testers distance 1M impose 1M / S of the speed relative to device doing radial movement, IF output is 5mV , 72Hz / S The pulsating signal, the output amplitude of the IF is approximately inversely proportional to the square of the distance.
