The HW-416-B features on the PCB for user calibration:

4.5V to 20V DC (typically powered via 5V) Static Current Consumption: < 60 µA Digital Output Level: High (3.3V) / Low (0V) hw-416-b pir sensor datasheet

Understanding the electrical and environmental limits of the HW-416-B is crucial for designing safe and long-lasting circuits. Specification 4.5V to 20V DC Can be powered by standard 5V or 12V rails Static Current Consumption < 50µA to 65µA Highly efficient for battery applications Output Signal Level High: 3.3V / Low: 0V Compatible with 3.3V and 5V microcontrollers Detection Distance Up to 3 to 7 meters Adjustable via onboard potentiometer (model dependent) Detection Angle < 100° to 120° cone Conical field of view shaped by the Fresnel lens Delay Time 0.5 seconds to 200 seconds Adjustable via onboard potentiometer Blockade Time 2.5 seconds Default blind period after output goes low Trigger Modes L (Non-repeatable) / H (Repeatable) Selected via jumper on the PCB Operating Temperature -15°C to +70°C Suitable for indoor and sheltered outdoor use PCB Dimensions Approx. 32mm x 24mm Standard standard PIR module footprint 3. Pinout and Hardware Configuration

Every object with a temperature above absolute zero emits infrared radiation. The HW-416-B contains a pyroelectric sensor split into two halves. The module incorporates a and EMC-certified layout ,

Controls how long the OUT pin remains HIGH after motion is detected. Turn clockwise to increase the delay time (up to several minutes). Trigger Mode Jumper:

If you are walking through a sensor's field of view, stop completely, and then start moving again, the sensor might miss the second movement because it is still stabilizing from the first. In robotics or high-speed detection scenarios, this latency can be an issue. However, for standard security and lighting, it is negligible. Specification 4
