Hw-416-b Pir Sensor | Datasheet

When a warm body passes from one zone to another, the sensor detects a differential shift in IR radiation.

The module typically features a 3-pin interface, making it compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. Power input (4.5V to 20V).

The HW-416-B provides an excellent balance of size and functionality. Its wide voltage tolerance (4.5V to 20V) means it can be safely used with standard 5V microcontrollers, 12V industrial systems, or battery banks, while its tiny static current draw ensures your power-conscious projects last as long as possible. hw-416-b pir sensor datasheet

Digital output pin. Outputs 3.3V (HIGH) when motion is detected and 0V (LOW) during standby. GND: Ground connection. Connect to the system ground.

PIR_PIN = 17 # GPIO17 connected to OUT

Accurately detects human movement within its range.

: The sensor is optimized to detect motion frequencies between 0.7 Hz and 30 Hz. When a warm body passes from one zone

Connecting the HW-416-B to an Arduino UNO is simple because the sensor outputs a clean digital signal. Wiring Diagram HW-416-B Pin Arduino Pin Digital Pin 2 Arduino Sketch

Most HW-416-B boards include three solder pads or header pins with a jumper labeled and L . The HW-416-B provides an excellent balance of size
