2,043 Reviews Scanned
- Adopts an exquisite metal enclosure of aluminum alloy. (MP3 only no WAV files)
- Equipped with a PIR motion sensor to trigger audio playback, and the detection range is up to 5 meters.
- Built-in 10W class D amplifier and the sound output is loud and beautiful.
- Able to connect to an external amplifier / active speaker through the 3.5mm audio jack.
- Dimension: 130*118*34.5(mm)
- [USE CASES]: The HC-SR501 PIR motion sensor is ideal for automated lighting, security systems, alarms, and motion-activated devices. It works flawlessly as a PIR sensor Arduino module or Raspberry Pi motion sensor, ensuring stable performance across various environments.
- [VOLTAGE RANGE & COMPATIBILITY]: Operating from 4.8V to 20V, this PIR sensor suits diverse power setups and integrates easily with Arduino, Raspberry Pi (all models including Pico/Pico W), RP2040 boards, and microcontrollers for fast prototyping.
- [ADJUSTABLE DETECTION]: The HC-SR501 offers adjustable sensitivity with a detection range of 3–7 meters, allowing precise tuning for PIR motion sensor projects in home automation or embedded systems.
- [SIMPLE OUTPUT MECHANISM]: On motion detection, the output pin switches to HIGH (“1”). Dual onboard potentiometers let you fine-tune delay time and sensitivity, improving performance in Arduino motion sensor applications.
- [COMPACT DESIGN & FOV]: A compact 32mm × 24mm board with a <100° cone angle and 23mm lens ensures wide, reliable field-of-view detection for DIY builds and embedded enclosures.
- Operating voltage range: DC 4.5-20V
- Quiescent Current: <50uA Trigger: L can not be repeated trigger/H can be repeated trigger(Default repeated trigger)
- Delay time: 5-200S(adjustable) the range is (0.xx second to tens of second)
- Board Dimensions: 32mm*24mm
- Angle Sensor: <100 ° cone angle Lens size sensor:Diameter:23mm(Default)
- WWZMDiB 5 Pcs PIR Sensor: When a human body enters the sensing range, the temperature difference between the body and the background causes a voltage change in the pyroelectric device. After amplification and comparison, the voltage signal is output.
- Voltage：DC 4.5-20V
- Detection Angle: <110 ° cone angle Lens size
- Detection range: 3-7 meters (10-23 feet)(adjustable)
- Two triggering modes: H: The output signal is maintained as long as a person is present. L: Triggered once with each change.
- Design with low power consumption and suitable to supply power using a 3.7V rechargeable lithium battery or 3 x AA / 3 x AAA alkaline batteries.
- Working voltage: 3.7-5V DC
- The distance of PIR detection: ≤3.5 meters
- Detection angle: 120 degrees
- Skill Level: Assembled and Tested
