The HW-416B features on the board that give you independent control over detection range and delay duration. These are the most important controls for tuning the sensor to your specific application.
If you need performance instead of guessing HW416B’s specs, use:
The module pairs a dual-element pyroelectric core (such as the RE200B) with a and an NL-11NH Fresnel lens. This combination creates 17 distinct detection zones across a wide viewing angle. hw416b pir sensor datasheet better
Integrating the HW-416B with an Arduino Uno, Nano, or ESP32 is straightforward since it outputs a clean digital signal. Wiring Diagram Connect HW-416B to Arduino 5V Connect HW-416B GND to Arduino GND Connect HW-416B OUT to Arduino Digital Pin 2 Optimized Arduino Sketch
Using the HW-416B is straightforward. Connect the OUT pin to any digital pin (e.g., D2). The HW-416B features on the board that give
Have a specific HW416B issue not covered here? Leave a comment or check the community forum links below. And if you found a better calibration trick, share it – that is how we all improve beyond the datasheet.
If motion continues, the sensor keeps the OUT pin high throughout the duration of the movement, restarting the timer. 5. Typical Application Circuit (Arduino Example) Here is a simple sketch to test your HW416B PIR sensor. This combination creates 17 distinct detection zones across
Let's break down the key specifications that matter for your projects.
Once you have the BISS0001 datasheet, you can reverse-engineer the HW416B’s exact resistor/capacitor values (R9, R10, C6, etc.) and even modify the time constants yourself.
The (often interchangeably labeled as the HC-SR501 ) is a versatile Passive Infrared (PIR) motion sensor commonly used in security systems, smart lighting, and DIY robotics. It detects movement by sensing changes in the infrared radiation emitted by warm objects, such as humans or animals. 1. Key Specifications Operating Voltage DC 4.5V – 20V (on-board regulator allows 5V-12V typical) Output Level Digital High (3.3V) when triggered; Low (0V) when idle Detection Range Adjustable from 3 to 7 meters Detection Angle Up to 110°–120° cone Delay Time Adjustable from ~0.3 seconds to 5 minutes (300s) Current Draw ~65mA active; very low standby (~50μA–65μA) Temperature Range -15°C to +70°C PIR Motion Sensor HW416B - Tayda Electronics
