Hw-416-b Pir Sensor Datasheet ((link)) File

sat atop a stack of breadboards, its white, faceted dome—the Fresnel lens—looking like a miniature igloo under the desk lamp. Leo was an inventor by night, and tonight, his mission was simple: build a security system for his snack drawer.

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: hw-416-b pir sensor datasheet

Activating a buzzer or sending a notification when movement is detected in a restricted area. sat atop a stack of breadboards, its white,

The onboard IC (e.g., BISS0001) processes this rapid differential voltage swing. If the swing passes a predefined threshold, the IC switches the OUT pin to 3.3V. The Role of the Fresnel Lens Turn clockwise to increase the delay time (up

When designing a circuit around the HW-416-B, staying within its electrical limits ensures longevity and prevents false triggering. Below are the core parameters typically found in its engineering datasheet: Specification / Value 4.5V to 20V DC (5V standard) Output Signal (Digital) High (3.3V) / Low (0V) Static Current Consumption < 50 µA to 65 µA Detection Distance 3 meters to 7 meters (adjustable via onboard potentiometer) Detection Angle < 100° to 110° cone angle Delay Time 0.5 seconds to 200 seconds (adjustable) Blockade Time 2.5 seconds (default) Trigger Modes L (Non-repeatable) / H (Repeatable - Default) Operating Temperature -15°C to +70°C PCB Dimensions Approx. 32mm x 24mm 3. Pinout and Hardware Configuration

The HW-416-B features a straightforward 3-pin interface alongside control components on the back of the PCB.
