100% Brand new Note: This product is a kit, buyers need to assemble their own. AA batteries are NOT included.Picture only for reference. contain 2pcs 2AA Battery holder. no 3AA Battery holder. How it works: In this study, the transistor as a switch. 1: No alarm. When a laser is irradiated onto the photosensitive resistor, transistor ended, active buzzer power off, stop chirping; light off. 2: Alarm.
