Hw-416-b Pir Sensor Datasheet | POPULAR · 2027 |
The HW-416-B is an electronic module designed to detect human or animal movement by measuring changes in the infrared (heat) levels emitted by surrounding objects.
is a versatile and cost-effective Passive Infrared (PIR) motion sensor module, frequently used in DIY electronics projects. Based on the widely popular
| Pin | Name | Description | |-----|--------|------------------------------------| | 1 | VCC | 4.5V – 20V DC power input | | 2 | GND | Ground | | 3 | OUT | Digital output (HIGH = motion) |
The onboard IC (e.g., BISS0001) processes this rapid differential voltage swing. If the swing passes a predefined threshold, the IC switches the OUT pin to 3.3V. The Role of the Fresnel Lens hw-416-b pir sensor datasheet
Flip the module over to locate two small, adjustable potentiometers:
Here are a few simple code examples in different programming languages.
The onboard IC processes this rapid pulse change, validates it against noise, and drives the OUT pin HIGH. 5. Circuit Diagram: Interfacing HW-416-B with Arduino The HW-416-B is an electronic module designed to
Adjustable from approximately 3 to 7 meters. Detection Angle: Approximately 110° to 120° cone. Operating Temperature: -15∘Cnegative 15 raised to the composed with power C +70∘Cpositive 70 raised to the composed with power C Pinout and Connections
When motion is detected, the output goes HIGH and stays HIGH for the set delay duration, then drops LOW. It ignores any movement during that delay period.
The flexibility of the HW-416-B allows it to be integrated into several real-world projects: If the swing passes a predefined threshold, the
Adjusts how long the output pin remains HIGH after motion is detected. Range is approximately 0.3s to 300s. Trigger Jumper (Yellow Cap): L (Non-repeatable):
Increases detection distance (up to ~7 meters).
