HaiWang HW-HB100L Microwave Radar Motion Sensor Module - 10-35m Range, IP65 Waterproof Casing

The provided specifications do not list a specific operating voltage. Typically, similar microwave radar modules operate on a DC supply, commonly 5V or 12V. You must consult the module's datasheet or wiring guide for the exact voltage requirements and ensure your power supply matches to prevent damage.

The HW-HB100L features user-adjustable potentiometers on the board for configuring the sensing range (10-35m) and the induction delay time (10s-30min). You will need to open the waterproof casing carefully to access these trim pots. Use a small screwdriver to turn them, testing the detection after each adjustment for your specific installation environment.

Yes, the module's IP65 waterproof rating means it is protected against low-pressure water jets from any direction and is dust-tight. This makes it suitable for outdoor use in typical weather conditions, including rain. However, it is not designed for submersion or high-pressure water cleaning.

The integrated photosensor measures ambient light levels (10-500 lux). You can set a threshold so the motion detection output is only active when the ambient light is below this level. This feature prevents lights from turning on during daylight hours, serving as an automatic day/night mode for energy-efficient operation.

This module provides a relay trigger output signal. It is designed to directly drive the coil of an external AC relay. The relay's contacts then switch the high-voltage AC load (like a light fixture). You must wire the module's output to the relay's control terminals and connect the AC load through the relay's switched contacts.
