Hw-416-b Pir Sensor Datasheet ((full)) Jun 2026

void setup() pinMode(2, INPUT); Serial.begin(9600); void loop() if (digitalRead(2) == HIGH) Serial.println("Motion Detected!"); delay(100); Use code with caution. Copied to clipboard

The HW-416-B uses a simple three-pin interface (VCC, OUT, GND), but also features a four-pin configuration header that allows advanced options.

The potentiometer labeled "Sensitivity" acts as a voltage divider into the BIS0001 chip. However, extensive testing shows that it does not significantly alter the physical range of the sensor in the way users expect. hw-416-b pir sensor datasheet

With a wide operational voltage range and dead-simple digital output logic, the HW-416-B is an essential asset in any maker's hardware toolkit.

Repeatable Trigger (Default) / Non-repeatable Trigger Operating Temperature: -15°C to +70°C void setup() pinMode(2, INPUT); Serial

Adjustable (typically from 0.5 seconds up to several minutes via onboard potentiometer)

The HW-416-B relies on pyroelectric technology to detect changes in infrared radiation emitted by moving objects (such as humans or pets). Below are the core electrical and physical parameters of the module: DC 4.5V to 20V (Commonly powered via 5V) Static Current Consumption: < 60 A (Ideal for battery-powered projects) However, extensive testing shows that it does not

One of the most convenient features of the HW-416-B for microcontroller users is its logic interface. It operates on a simple High/Low digital logic:
