Hw416b Pir Sensor Datasheet Better Online
Since there isn't a widely distributed commercial component specifically labeled "HW416B" in major component databases (it is likely a house-marked version of a generic PIR module, similar to the HC-SR501 or SR602, or a typo for the HW-416 relay module), this review focuses on the most probable candidate: generic compact PIR sensor modules often found under similar part numbers on Amazon, AliExpress, and electronics kits.

The HW416B PIR sensor datasheet provides a good overview of the sensor's specifications, features, and application information. While there is room for improvement, the datasheet is generally clear and concise, making it easy for users to understand and work with the sensor. With some additional information and examples, the datasheet could be even more helpful for designers and engineers working with the HW416B PIR sensor. hw416b pir sensor datasheet better
pinMode(PIR_PIN, INPUT_PULLDOWN);
- VCC (Left) : Power (4.5V–20V)
- OUT (Middle) : Digital Signal (3.3V)
- GND (Right) : Ground
| Parameter | Typical Value | |-----------|----------------| | Operating Voltage | 5V – 20V (but 5V works fine) | | Standby Current | < 50 µA | | Output High | 3.3V (not 5V – be careful) | | Output Low | 0V | | Delay Time | 5 – 300 seconds (adjustable) | | Sensitivity | 3 – 7 meters | | Trigger Modes | Single (non-repeatable) or Repeatable | Since there isn't a widely distributed commercial component
