Output goes high, then low, regardless of continued motion. 6. Arduino Example Code The following code detects motion and lights up an LED.
It is ideal for projects requiring automated light activation, burglar alarms, and occupancy detection. 2. Technical Datasheet & Specifications (HW-416-B) hw-416-b pir sensor datasheet
When designing your next motion-sensing project, remember: Output goes high, then low, regardless of continued motion
The HW-416-B PIR sensor is an easy-to-use and reliable module that allows you to add motion detection to any of your projects. With its straightforward three-pin interface, adjustable settings, and wide operating voltage, it is well-suited for many DIY and professional designs. Whether you're building a security system or automating your home, the HW-416-B is a strong choice. It is ideal for projects requiring automated light
| Pin | Name | Description | |-----|------|-------------| | 1 | VCC | Power supply (5V typical, compatible with 4.5V–20V) | | 2 | OUT | Digital output: HIGH (3.3V) on motion detection, LOW when idle | | 3 | GND | Ground connection |
: Controls how long the "High" signal persists after motion is detected.
