HW-XC901 Microwave Sensor Module with 5.8G Fix Frequency Can Used outside for Street Light

HW-XC901 Microwave Sensor Module with 5.8G Fix Frequency Can Used outside for Street Light

The HW-XC901 is a dual-plate superimposed microwave induction 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 the output is 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 is capable of penetrating the shell for induction (with the exception of the metal shell), and the distance will undergo corresponding attenuation, typically around 10% - 20%.

It is not influenced by temperature and humidity. The inductive sensitivity has no directionality.

In a small room, the reflection from the walls enables 360-degree induction with no blind spots.

A CDS welding position is reserved to add the light control function.

● Repeat trigger: After the first trigger, when the sensing area is triggered again, the module delay time will be superimposed again when the first trigger time is not stopped. (For example, the module delay is 10S, the sensing signal is received again in 10S, and then 10S is superimposed. If there is no interruption in 10S, there will always be an output signal) ● Delay time: refers to the duration of the high voltage signal output. Regardless of the delay, the delay is in milliseconds and can be rushed.

Detection diagram

During dynamic sensing, the 2 pin outputs a high level, the MOS is turned on, and the power supply has a DC load circuit to the MOS, and the LED will be in a lit state.

The daytime mode CDS works, and the CDS-led is in the light state, indicating that the light is in a working state. (The photosensitive working condition is that the light is valid when the module is low level, and the photosensitive light is invalid when the module outputs a high level)

Precautions

Installation Precautions:

During installation and testing, maintain a minimum distance of 5mm between the module antenna board (S-shaped open PCB) and any objects or the outer casing to prevent interference.

Initialization Time:

After powering on, allow for an initialization period of approximately 5 seconds. Any anomalies during this period should be noted and addressed promptly.

Output Current Consideration:

The module's output current is relatively weak. To avoid false alarms, refrain from directly driving a load. Consult the wiring diagram for proper installation instructions.

Module Placement Recommendations:

To prevent signal interference, avoid installing multiple modules facing each other within the effective sensing range.

Power Supply Requirements:

Utilize a stable DC power supply with consistent output voltage, current, and ripple coefficient. Unstable power supplies may lead to issues such as false alarms, lack of induction, or cyclic restarts.

Impact of Surroundings on Sensing:

In environments with reflective surfaces like walls or obstacles, the sensing distance and angle may increase. Conversely, in open spaces, the sensing distance and angle may decrease by approximately 20%. Be aware of these variations in different surroundings to optimize module performance.
