In the quiet hum of Leo’s cluttered workshop, a single HW-416B PIR sensor
Do not point the sensor toward heaters, air conditioners, or direct sunlight, as rapid temperature changes can cause false positives.
Digital TTL (High = 3.3V, Low = 0V), making it compatible with both 3.3V and 5V microcontrollers like Arduino, ESP32, and Raspberry Pi.
