HW-HB100 microwave sensor module

Overview

The HW-HB100 is a dual-plate superimposed microwave sensing module. According to the Doppler effect principle, a high-frequency electromagnetic wave is transmitted and received by a planar antenna, and then a small movement change of the folded-back wave is detected, thereby triggering the microprocessor to work, and finally outputting useful Control level (H-1/L-0) or control status.

It is suitable for secondary development in other electronic fields such as intelligent electrical appliances, security products, and lighting products. This product can be widely used in security monitoring, intelligent control systems, lighting appliances (garage, corridor, road and other places).

Characteristics

    ● It can penetrate the shell induction (except for the metal shell), and the distance will have corresponding attenuation, generally about 10%-20%.

    ●It is not affected by temperature and humidity. Inductive sensitivity is not directional.

    ●The small room is reflected by the wall, which can achieve 360 degree induction and no dead angle.

    ●Retain the CDS welding position and add the light control function.

Detection diagram

The 2-pin output signal is 3.3V. When there is induction, the LED is on, and the module output works normally.

The product is reserved for SENS, TIME, and CDS. It is a custom PWM setting function for customers. It can define the module sensitivity, sensing time and light sensitivity.

Precautions

●When installing and testing the product, please keep the module antenna board (S-shaped open PCB) at least 5mm in front of it, and it should not be close to the object or the outer casing.

● There is approximately 5 s initialization time after power-on, during which time it is abnormal.

● The output current of the module is very weak. If the load is directly driven, it will cause a false alarm. Please refer to the wiring diagram.

● Try to avoid installing two or more modules face to face within the effective sensing range.

● Please use DC power supply with output voltage, current and ripple coefficient, etc. The power supply will be unstable, there will be false alarm, no induction, and the cycle will start.

● In the case where there are walls or obstacles reflecting microwaves around, the sensing distance and angle will have a gain. In the case of relatively empty surroundings, the sensing distance and angle will be attenuated, and the difference is about 20%.
