Pir Sensor Datasheet =link= | Hw-416-b

The module exposes three interface pins, typically clearly labeled on the bottom silk-screen of the PCB: Input power supply (4.5V – 20V DC).

Note: The sensor is usually powered via VCC and GND, and the OUT pin sends a signal to a microcontroller (like Arduino, Raspberry Pi) or a transistor to trigger a relay. 4. Hardware Adjustments (Potentiometers & Jumpers)

The HW-416-B features two potentiometers (yellow knobs) and one jumper for customizing behavior. 4.1 Sensitivity Adjustment (Potentiometer) hw-416-b pir sensor datasheet

The (often cross-referenced with the HC-SR501 ) is a versatile, low-cost passive infrared module widely used in DIY electronics, security systems, and automated lighting. This article provides a comprehensive technical overview and datasheet-style guide for the HW-416-B. Technical Specifications

The is a passive infrared (PIR) motion sensor module, widely recognized as a variant or rebranded version of the popular HC-SR501 PIR sensor . It uses the BISS0001 controller chip to detect human presence by measuring changes in infrared radiation. Core Specifications The module exposes three interface pins, typically clearly

The back of the PCB features two miniature potentiometers (trimpots) that can be adjusted carefully using a small screwdriver.

: The output goes high and then low regardless of whether the person is still moving in the range. 5. Application Benefits Technical Specifications The is a passive infrared (PIR)

These specifications show the HW-416-B is suitable for many indoor motion-sensing applications. Its wide voltage range and low power consumption make it ideal for battery-powered, IoT, and energy-harvesting projects.
