from a wide area onto the small pyroelectric element.

Digital signal output (3.3V Logic). Connects directly to any microcontroller digital input pin. GND: Ground connection (0V). Onboard Adjustments

Turning this clockwise increases the detection distance (up to ~7 meters). Turning it counter-clockwise reduces the range (down to ~3 meters). hw-416-b pir sensor datasheet

PIR_PIN = 17 # GPIO17 connected to OUT

Connecting the HW-416-B to your microcontroller is straightforward.

Pairing the HW-416-B with a buzzer or GSM module to alert homeowners of entry. Complete Technical Guide and Datasheet Analysis for the

The is a high-performance passive infrared (PIR) motion sensor module, frequently used as a direct, reliable replacement for the standard HC-SR501 . It detects human and animal movement by sensing changes in infrared radiation emitted by warm objects. Core Specifications is electrically and physically identical to the Go to product viewer dialog for this item.

Passive Infrared (PIR) sensors are the backbone of modern security systems, automated lighting, and smart home robotics. Among the various budget-friendly modules available to makers and engineers, the stands out for its compact form factor, reliability, and ease of integration.

Decreases detection distance (down to ~3 meters). 2. Time-Delay Adjustment

This lens is divided into multiple facets or zones. As a warm body moves across these zones, the amount of infrared radiation hitting the pyroelectric element changes rapidly. The onboard control circuitry processes this fluctuation and toggles a digital output pin to signal that motion has been detected. 2. Technical Specifications (Datasheet Reference)

Triggering sirens, snapshot cameras, or sending push notifications via Wi-Fi modules (ESP8266/ESP32).
