The following parameters are standard for the HW-416-B module: Specification DC 4.5V – 20V Quiescent Current < 50µA (ideal for battery use) Output Signal Digital (High 3.3V / Low 0V) Detection Distance Adjustable (3 meters to 7 meters) Delay Time Adjustable (5 seconds to 300 seconds) Detection Angle < 110° cone angle Operating Temp -15°C to +70°C Trigger Modes L (Non-repeatable) or H (Repeatable) Pinout and Interface
Power ON │ ├── Warm-up (~30-60s) – output remains LOW/random │ ▼ Idle – OUT = LOW │ ├── Motion detected ──► OUT = HIGH │ │ │ ├── If retriggering (H): timer resets on each new motion │ └── If single (L): timer runs once │ ▼ Delay ends – OUT = LOW hw-416-b pir sensor datasheet
This sensor detects movement by sensing changes in infrared radiation emitted by living organisms, typically within a range of . Technical Specifications (Datasheet Summary) The following parameters are standard for the HW-416-B
The HW-416-B is a cost-effective, low-power solution for motion detection. Its adjustable parameters (sensitivity and delay) and standard digital output make it highly versatile for both hobbyist and commercial applications. While it lacks advanced features like UART output found in newer "smart" PIRs (e.g., RCWL-0516), its reliability and ease of use make it an industry standard for basic motion sensing. While it lacks advanced features like UART output
