Hw-416-b Pir Sensor Datasheet !free!

The HW-416-B is a passive infrared (PIR) motion sensor module based on the HC-SR501 design. It detects changes in infrared radiation (body heat) within its field of view. It is widely used for human/animal motion detection in security systems, automatic lighting, and IoT projects.

The sensor operates by detecting infrared radiation emitted by the human body. Operating Voltage: 4.5V to 20V DC (5V recommended). Static Current: Output Signal:

High/Low Digital TTL logic (High = 3.3V, Low = 0V) hw-416-b pir sensor datasheet

The output stays high as long as continuous movement is detected within the sensor's field of view. Applications for the HW-416-B

The is a reliable, low-power motion detection module ideal for hobbyist and industrial prototypes. This article has provided a complete datasheet covering electrical specs, pinouts, potentiometer adjustments, trigger modes, and real-world wiring examples. The sensor operates by detecting infrared radiation emitted

When a warm body (like a person) moves across the sensor's field of view, the infrared level changes rapidly. The crystal generates an electrical charge in response to this change, triggering the alarm.
