Hw-416-b Pir Sensor Datasheet

Power input. Connect to a 5V supply line (compatible with 4.5V–20V).

As noted in the component datasheet, the BISS0001 can be paired with a pyroelectric infrared sensor and a few external components to create a complete passive infrared switch system suitable for burglar alarms, automatic lighting, automatic doors, electric fans, and hand dryers.

Pairing the HW-416-B with a buzzer or GSM module to alert homeowners of entry.

. It is designed to detect motion by sensing changes in infrared radiation emitted by objects like human bodies. Key Technical Specifications Based on documentation from Tayda Electronics Popular Electronic

Digital TTL High (3.3V) when motion is detected; Low (0V) otherwise. Detection Range: 3 to 7 meters (adjustable via potentiometer). Detection Angle: Approximately 110° to 120°. Delay Time: 0.3 seconds to 5 minutes (adjustable via potentiometer). Operating Temperature: -20°C to +80°C. Pinout Configuration How PIR Sensor Works and How To Use It with Arduino

Digital output. Stays HIGH (3.3V) when motion is detected and LOW (0V) when idle. Connect to the common ground of your circuit. Adjustable Controls Sensitivity Potentiometer:

Here is an interesting technical report summary based on reverse-engineering the HW-416/HC-SR501 hardware.

Adjustable (typically from 0.5 seconds up to several minutes via onboard potentiometer)

To help refine this documentation for your project, let me know: What or platform are you planning to use?

Functionally identical; only PCB layout and color differ.

The board also uses a to convert the input voltage (whether 5V or higher) down to 3.3V for the internal logic circuitry.

This sketch turns on an LED when motion is detected and prints messages to the Serial Monitor.

Less than 120-degree cone angle, up to 7 meters (adjustable via potentiometer) Operating Temperature: -20°C to +80°C Dimensions: Approx. 32mm x 24mm 2. Pinout and Hardware Configuration
