Signal output pin. Outputs 3.3V High when motion is detected and 0V Low when idle.

The (frequently cross-referenced with the ubiquitous HC-SR501 framework ) is a highly efficient, low-cost passive infrared detector designed to sense human or animal movement. Based on the robust BISS0001 micro-power PIR IC decoder , this board integrates an onboard pyroelectric element, signal-conditioning logic, and a multi-zone Fresnel lens dome . It is fully compatible with popular 3.3V and 5V microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi. 📋 Comprehensive Technical Specifications

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

At the core of the HW‑416‑B is the integrated circuit, a dedicated PIR signal‑processing chip. It takes the tiny signal from the pyroelectric sensor, amplifies it, filters out noise, and produces a clean digital output when motion is detected. This IC is designed for low power consumption and good immunity against radio‑frequency interference.
