The HW-416B supports two operational modes, selected via a jumper on the board. This is one of the most overlooked yet powerful features of the module.
The HW-416B is a passive infrared (PIR) motion sensor module that detects changes in infrared radiation, typically from a human body moving within its field of view. It's commonly sold under several names, including HW-416-B and is often described as an HC-SR501 variant. However, the HW-416B has a crucial design difference: in addition to the three main connection pins (VCC, GND, OUT), it features an extra set of configuration pins used to adjust the device's behavior.
The is a highly popular, low-cost Passive Infrared (PIR) motion sensor module , frequently identified as a variant of the widely used HC-SR501 . It is a "passive" device, meaning it does not emit energy but instead detects changes in infrared radiation (heat) emitted by humans or animals moving within its field of view. Technical Specifications PIR sensors are sensitive to power supply noise
The is one of the most reliable and widely implemented motion-sensing modules available for electronics enthusiasts, hardware engineers, and DIYers alike. Often sold interchangeably under the iconic HC-SR501 designation , understanding its technical specifications is critical to unlocking its full potential.
The module typically features three main pins and two potentiometers for fine-tuning. Power input (5–20V).
To change modes, simply move the jumper on the module to the desired position—no soldering required. This is one of the most overlooked yet
is a variant of the widely used passive infrared (PIR) motion sensor module. It is designed to detect infrared radiation emitted by moving heat sources, such as human bodies or animals, within a specific range. Tayda Electronics Key Technical Specifications
Suggested post body: "Hi — I have an HW416B PIR motion sensor but can't find an official datasheet. I need: operating voltage, output type (active high/low), sensitivity/range, timing (retrigger/hold) and pinout. If anyone has a datasheet or test measurements, please share. Also welcome recommendations for better-documented replacement PIR modules compatible with 3.3–5V microcontrollers."
Passive Infrared (PIR) sensors are the backbone of motion-activated systems, ranging from security cameras to smart home lighting. While many sensors look similar, the (often listed alongside or as a variant of the HC-SR501) has established itself as a reliable, flexible, and better-performing module compared to cheaper, generic alternatives .
