Hw-416-b Pir Sensor Datasheet Portable (2024)

is a compact Passive Infrared (PIR) motion sensor module widely used in DIY electronics and security systems. It is essentially a variant of the popular , sharing a similar footprint and operation. Key Technical Specifications

Last updated: October 2025. Specifications are based on Revision 2.3 of the HW-416-B board. Always verify with your specific module version. hw-416-b pir sensor datasheet

• Operating Voltage: 3.3V - 5V
• Current Consumption: 50μA (typical)
• Detection Range: 5-7 meters (adjustable)
• Detection Angle: 110° (horizontal), 60° (vertical)
• Output Signal: Digital high/low signal (VCC/0V)
• Delay Time: Adjustable (typically 2-10 seconds)
• Temperature Range: -20°C to +80°C

It was set to the center, which meant the sensor would stay active for three minutes after one tiny movement. With a small screwdriver, he turned it fully counter-clockwise, reducing the delay to a snappy three seconds. The Sensitivity Pot: is a compact Passive Infrared (PIR) motion sensor

• Standby: ~50–80 µA
• Active: ~50–60 µA (sensor element); output driver current depends on load
