Hw-416-b Pir Sensor Datasheet
Digital output signal (Connect to an Arduino digital pin or a relay module). GND: Ground connection. Key Features & Usage Immunity to Interference: Unlike larger sensors, the
This code monitors the HW-416-B sensor. When motion is detected, it illuminates the built-in Arduino LED (Pin 13) and prints a alert message to the Serial Monitor. hw-416-b pir sensor datasheet
