Hw-416-b Pir Sensor Datasheet Jun 2026

: Controls how long the "High" signal persists after motion is detected.

| Feature | Common Assumption | Technical Reality | | :--- | :--- | :--- | | | Custom IC | BIS0001 (Generic PIR Controller) | | Distance Pot | Adjusts range (meters) | Adjusts Amp Gain (sensitivity to motion size) | | Time Pot | 0.3s to 5 mins | Determined by RC constant on Chip Pin 8; usually accurate to the label. | | Logic Mode | Always ON when moving | Requires soldering jumper to 'H' for "Always ON" behavior. | hw-416-b pir sensor datasheet

The module typically features three main pins for connection and two potentiometers for fine-tuning performance. Connect to 5V–20V power source. : Controls how long the "High" signal persists

If you are looking for a standard PDF datasheet for the HW-416-B, you likely won't find one from a major manufacturer. These sensors are generic modules produced by various Chinese factories. | The module typically features three main pins

The is one of the most popular and cost-effective Passive Infrared (PIR) motion sensor modules available in the electronics market. Often found in Arduino starter kits, security lighting projects, and automatic door systems, this module is frequently compared to its predecessor, the HC-SR501. However, the HW-416-B offers distinct advantages in terms of size, power consumption, and adjustability.
