Product Detail

This microwave detector, it dedicated microprocessor, not only high detection sensitivity, detection range, and very reliable, very low false positive rate, within the temperature range of -25~+50 stability, optimal and in medium and top grade burglar alarm systems in the human body or object motion detection sensor used.

First, Working Principle:

1.1 Detector, using micro-antenna in to axis direction produced a oval RADIUS for 0~7 m (can adjusting) space microwave alert area, for weaker of interference signal, as small volume of animal, far distance of trees shook, and high frequency communications signal, and distance of lightning and household appliances switch Shi produced of interference be taking into account except, dang detector identification out human or objects moved Shi, control circuit is triggered, output a, and b closed, delay output 3-5 seconds around.

1.2 Detector alarm led 1 green, human are detected, or when objects move, the Green led is lit. Set the sensitivity adjustment potentiometer on PCB RP1, adjustable within monitoring distance of 0.5~7 m, clockwise from the past, turning it counterclockwise far distance from.

1.3 When the detector is powered for the first time, the system self test, delayed about 1 minute, output self 3 times green light flashing 3 times then when you detect people or objects moving, 3-5 second signal will be output if the body or objects in the context of monitoring activity, constant alarm.

1.4 Detector wiring diagram as shown, the output pitch 2.54mm, 4pin socket, in addition, for the convenience of customers, with a 4pin line of 150mm.

Terminals are described as follows:

1, - --- Power negative (GND).

2, + --- positive power supply (+ 12V).

3, A --- 1 relay output.

4, B --- 2 Relay output.

1.5 detector work very reliably, generally no false positives, the alarm circuit and a conventional microwave circuits previous infrared, ultrasonic, pyroelectric element composed unmatched, is the best product currently used for security and automatic monitoring, so ideal for use in warehouses, shopping malls, museums, or the financial sector, with the installation covert, big monitoring range, low system cost.

Second, the use precautions:

2.1 microwave signal generated by the detector may cause the transmission, reception and processing of amplifying trace noise and improve sensitivity noise will cause false triggering, the detector can detect the human body or object farthest move 14 meters distant, but too sensitive and prone to false positives, generally recommend that users use less than 7 meters, normal sensitivity adjustment potentiometer connected to 3 to 4 steps to move triggered best at 5 meters.

2.2 detectors installed indoors as much as possible against the top corner, axially aligned windows site installation, should pay attention to wind waterproof outdoor and reduce sensitivity to use.

2.3 detectors should be used 12V 100mA DC power supply, and to ensure that any time the supply voltage is not less than 10.5V, in order to make the circuit stability, if high loudness alarm and detector utility power, the power capacity of not less than 500mA, and try the detector and high loudness alarm separated to avoid mutual interference.

2.4 belong to the output of the detector relay terminal output, so with a multimeter resistance profile, can directly measure whether there is output, when there is an output, two contact closure relay terminals, A, B resistance between zero and green warning lights, no alarm output, A and B open, the resistance is infinite, green warning lamp.

Three, main technical parameters:

3.1 Supply voltage: + 12V DC.

3.2 Monitoring range: 7 meters effective, as far as you can reach 14 meters, the user can adjust according to the actual use of the environment, as long as you can reach the scope of monitoring to minimize the sensitivity and reduce false positives.

3.3 Output Type: relay contact output, contact current max 1A.

3.4 Dimensions: length 50 x width 30 x height 20mm

Package Included:
1x DC 12V Microwave Radar Sensor Body Motion Detector Switch Module
