Hw-416-b Pir Sensor Datasheet [LATEST]

While the specific model number appears to be a variance or specific batch code of the standard HC-SR501 PIR sensor (commonly found in Arduino starter kits), the "interesting report" regarding this device isn't a standard datasheet. Instead, the most compelling technical analysis focuses on the incredible complexity hidden inside a cheap sensor and the common myths about its potentiometers .

The is a standard Passive Infrared (PIR) motion sensor module, frequently used in DIY electronics projects with microcontrollers like Arduino, Raspberry Pi, and ESP32. It is essentially a variant of the widely documented HC-SR501 module. Technical Specifications Operating Voltage: typically 4.5V4.5 cap V 12V12 cap V Output Signal: Digital HIGH ( 3.3V3.3 cap V ) when motion is detected; Digital LOW ( ) when idle. Detection Range: Adjustable up to meters (approx. Detection Angle: Approximately 110∘110 raised to the composed with power Quiescent Current: Extremely low, often less than Time Delay: Adjustable from approx. seconds to seconds via on-board potentiometer.
