Hw-416-b Pir Sensor Datasheet 2021
HW-416-B
While the specific model number appears to be a variance or specific batch code of the standard HC-SR501 PIR sensor (commonly found in Arduino starter kits), the "interesting report" regarding this device isn't a standard datasheet. Instead, the most compelling technical analysis focuses on the incredible complexity hidden inside a cheap sensor and the common myths about its potentiometers .
- Operating Voltage: 4.5V – 20V DC (5V – 12V recommended)
- Static Current: < 50 µA (ultra-low power consumption)
- Output Signal: 3.3V TTL logic (HIGH when motion detected, LOW when idle)
- Delay Time (Tx): 0.3 sec – 600 sec (adjustable via potentiometer)
- Block Time (Tb): 2.5 sec (fixed; sensor ignores new triggers during this period)
- Trigger Modes: Single trigger (non-repeatable) / Repeatable trigger (jumper selectable)
- Detection Range: Up to 7 meters (adjustable)
- Detection Angle: < 110° cone (lens dependent)
- Operating Temperature: -15°C to +70°C
- PCB Dimensions: 32 mm × 24 mm × 28 mm (with lens)
