WWZMDiB 5 Pcs PIR Sensor Compatible with HC-SR501 PIR Motion Module (with 2 cases)
Quick take
This WWZMDiB 5-pack PIR sensor set is meant for DIY motion-detection builds using HC-SR501-compatible modules, commonly with Arduino, Raspberry Pi, and STM32. It supports adjustable detection distance (about 3 to 7 meters) and two output behaviors (repeat while motion is present, or trigger once per change). The main caveat is that the sensor modules require the usual DC power (DC 4.5 to 20V) and you will need a compatible control input setup for your project.
Pros and cons
Pros
- Five sensors for prototyping multiple zones or building more than one device.
- Configurable range and sensitivity, with an adjustable detection distance around 3 to 7 meters.
- Two triggering modes (repeat while present, or trigger once per motion change).
- Works well for typical maker projects like Pi camera and ESP32-style installations.
Cons
- Battery-powered operation is indicated, but battery is not included, and you still need the correct DC supply (DC 4.5 to 20V) for the module.
- Best suited for DIY motion sensing projects, not for plug-and-play standalone consumer security devices.
What buyers think
Buyer feedback is generally positive and focused on real-world project use. Multiple reviews describe the sensors as working as expected for PIR motion detection, including microcontroller-based builds. Buyers also highlight that sensitivity can be useful for certain setups, and that installation details (like mounting and module controls such as potentiometers/jumper selection) make it straightforward to integrate into projects like Raspberry Pi camera monitoring and ESP32 mesh-style applications. Review evidence is limited to short snippets, so performance consistency across every environment (lighting conditions, mounting height, and indoor versus outdoor use) is not deeply characterized, but the overall pattern points to a reliable maker-friendly PIR module.
Key specs that matter for DIY buyers
Power and output behavior
These PIR sensors are specified to operate with a DC supply of 4.5 to 20V. They are also intended for motion-module style use, with an output behavior controlled by a mode selection. In “H” mode, the output signal remains while a person is present. In “L” mode, the sensor triggers once with each change.
Detection range and angle
The stated detection range is adjustable from roughly 3 to 7 meters (10 to 23 feet). The detection angle is listed as a cone angle of under 110 degrees. Practically, this means your mounting position and aiming direction will matter if you are covering a doorway, hallway, or a narrow corridor.
Compatibility with HC-SR501-style module setups
The set is labeled as compatible with HC-SR501 PIR motion module usage, which is a common approach for Arduino, Raspberry Pi, and STM32 projects. If your existing wiring expects typical HC-SR501 pinout and control behavior, this kit is designed to fit that same workflow.
Pros and cons for specific projects
Best for
- Maker projects that need multiple PIR sensors, such as multi-room or multi-zone detection.
- People building motion-triggered automation, lighting, or simple notification systems using microcontrollers.
- Projects that can take advantage of adjustable sensitivity and the repeat-versus-trigger-on-change mode.
You may want to skip it if
- You want a fully standalone, off-the-shelf security sensor with no wiring or module configuration.
- You need a very specific commercial-grade form factor, long-term environmental sealing, or tested outdoor durability (not covered by the available evidence).
Installation and setup considerations
A recurring theme in buyer notes is that integrating PIR sensors is manageable when you understand the module’s controls. The kit includes dedicated cases, and reviews mention mounting hardware and module adjustment components that help you set detection behavior and range. If your project reads a digital output, you will also want to plan for how your firmware should handle either “stays high while motion is present” behavior or the “single trigger per change” behavior.
Alternatives (how to choose without naming brands)
If you are comparing PIR options, base your choice on what you need most:
- More modules in one kit: a multi-pack like this can reduce per-sensor cost for multi-zone builds.
- Different output behavior: confirm whether the sensor or module supports repeat-during-presence versus trigger-on-change logic.
- Range and angle requirements: choose based on your mounting distance, expected detection direction, and how wide a zone you need to cover.
- Power and wiring comfort: if you need low-voltage or battery-only operation with a specific power profile, verify the sensor module’s voltage requirements and whether batteries are included.
Verdict
WWZMDiB’s 5-pack PIR sensor set is a solid pick for DIY motion detection where HC-SR501-style module behavior fits your design. The mix of adjustable range, two triggering modes, and a multi-sensor bundle makes it especially useful when you want to build or test more than one detector. The main thing to confirm before buying is your power and wiring plan, since these modules rely on DC power and battery inclusion is not indicated.

FAQ
How far can these PIR sensors detect motion?
The listed adjustable detection range is approximately 3 to 7 meters (10 to 23 feet). Actual performance depends on mounting height, aiming direction, and sensitivity settings.
What triggering modes do these sensors support?
They support two modes: one where the output stays active as long as a person is present (H mode), and one where it triggers once per change (L mode).
What power do the modules need?
The voltage specification is DC 4.5 to 20V. Battery power is referenced, but a battery is not included.
Are these compatible with Raspberry Pi and Arduino projects?
They are intended for HC-SR501 PIR motion module-style integration, which is commonly used with microcontroller projects including Arduino and Raspberry Pi.
Is this kit a good choice for a standalone security device?
It is better suited for DIY builds where you handle wiring and module configuration. If you need a fully standalone security sensor with minimal setup, you may prefer a purpose-built consumer device.
