Hw-416-b Pir Sensor - Datasheet [work]
The HW-416-B PIR sensor can be used in various applications, including:
| Pin Name | Function | Description | | :--- | :--- | :--- | | | Power Input | Connect to +5V DC (or 4.5V–20V). Do not exceed 20V. | | GND | Ground | Common ground with the microcontroller or load circuit. | | OUT | Digital Output | Goes HIGH (3.3V) when motion is detected. Falls LOW after lock-down time. |
The PCB typically includes reserved solder pads for a photoresistor (to disable the sensor during daylight) and a thermistor (for temperature compensation). Pinout and Connection Guide PIR Motion Sensor HW416B - Tayda Electronics hw-416-b pir sensor datasheet
Turning clockwise increases the detection distance.
The sensor output goes low once the delay time expires, even if motion continues. Repeatable Trigger (H): The HW-416-B PIR sensor can be used in
if (motionState == HIGH) digitalWrite(ledPin, HIGH); Serial.println("Motion Detected!"); delay(100); else digitalWrite(ledPin, LOW);

The HW‑416‑B is versatile and can be used in a wide range of projects:
The HW-416-B is designed for reliability and ease of use. It operates by detecting changes in infrared radiation (heat) from moving objects like humans or animals. Operating Voltage: 5V to 20V DC. Static Current: Output Level: High 3.3V / Low 0V (TTL logic). Sensing Range: Up to 7 meters (adjustable). Detection Angle: 110 raised to the composed with power cone angle. Delay Time: 0.3 seconds to 5 minutes (adjustable). Block Time: Default 2.5 seconds. Pinout and Hardware Configuration
Note: Always let the PIR sensor warm up for 30–60 seconds after powering on. During this time the output may be erratic or stay HIGH, but it will stabilise once the sensor has calibrated to the ambient conditions.
