This guide serves as a functional datasheet and implementation manual for engineers and hobbyists alike. 1. Technical Specifications

Key specifications for the HC-SR501—functionally identical to the HW-416-B—confirm the wide input voltage range from 4.5V to 20V, making it compatible with both 3.3V and 5V logic systems. hw-416-b pir sensor datasheet

Some early HW-416-B modules have an additional jumper for 5V/3.3V output selection, but the standard version is fixed at 3.3V logic. Always check your specific board revision.

In this post, we’ll break down the technical specifications, pinout, and key features to help you integrate it into your next build. Core Specifications Some early HW-416-B modules have an additional jumper

This is the standard wiring used with most microcontrollers. The pin can be connected directly to a digital input pin of an Arduino, ESP8266, ESP32, or Raspberry Pi.

This comprehensive guide serves as an expanded technical datasheet and implementation manual for the HW-416-B module. Technical Specifications and Features Core Specifications This is the standard wiring used

| Pin | Name | Description | |-----|------|-------------| | 1 | VCC | Power input (4.5V – 20V DC) | | 2 | OUT | Digital output (HIGH = motion detected, LOW = idle) | | 3 | GND | Ground (0V) |

The HW‑416‑B has three main pins, plus two extra pins that allow 3.3 V operation.
