Hw-416-b Pir Sensor | Datasheet

The HW-416-B PIR sensor module typically has three pins:

The is a widely used Passive Infrared (PIR) motion sensor module , favored by hobbyists and engineers alike for its compact size, low power consumption, and reliability. Often found in DIY security systems, automated lighting, and robotics, this sensor is a staple for detecting human presence. hw-416-b pir sensor datasheet

⚠️ The sensor needs 10–60 seconds to calibrate after power-on. During this time, it may trigger falsely or stay LOW. This is normal. The HW-416-B PIR sensor module typically has three

detects motion by measuring changes in the infrared levels emitted by surrounding objects Operating Voltage: 4.5V to 20V DC. Voltage Output: High/Low signal (3.3V High, 0V Low). Detection Range: Adjustable up to approximately 7 meters (23 feet). Detection Angle: Less than 120°. Delay Time: During this time, it may trigger falsely or stay LOW

Typically 5V to 20V DC (includes an onboard 3.3V regulator).
