El hermanito pequeño del sensor PIR normal; la cabeza tiene un diámetro de solo 1,1cm
Pines:
- Vin (indicado con "+" y/o "U1")
- Out (pin central)
- GND/ground/min (indicado con "-" y/o "C1")
Dimensiones
Longitud: 2,8cm
Anchura: 1,4cm

Así conectas el Mini sensor de movimiento infrarrojo piroeléctrico PIR a un Arduino UNO o ESP32, con un sketch de ejemplo que puedes subir directamente.
Este proyecto detecta movimiento usando un sensor PIR mini y activa el LED integrado del Arduino. Cuando se detecta movimiento, el LED se enciende y se muestra una notificación en el Serial Monitor. Deja un breve tiempo de calentamiento después de encenderlo para que el sensor se estabilice.

Este proyecto detecta movimiento humano usando un sensor de movimiento Mini PIR. Cuando se detecta movimiento, el ESP32 enciende el LED integrado (GPIO 2) y registra un mensaje en el Serial Monitor. Alimentar el sensor con 3.3V garantiza niveles de señal seguros para la entrada del ESP32.
