Hw416b Pir Sensor Datasheet Better Fix

Most "datasheets" show a blurry image. Here is the clear pinout:

The HW416B PIR sensor uses a pyroelectric sensor to detect infrared radiation emitted by the human body. The sensor has a high sensitivity and can detect temperature differences as small as 0.1°C. hw416b pir sensor datasheet better

The HW416B can be better for low-power, 3.3V systems (ESP32, Raspberry Pi Pico) if you follow the power filtering advice above. Otherwise, the HC-SR501 is more forgiving. Most "datasheets" show a blurry image
