Product Description
Note: This product is assembled. AA batteries are NOT included. contain 2pcs 2AA 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. When the laser is blocked, no light exposure to the photosensitive resistor, the transistor is turned on, the buzzer to get the power starts singing while working indicator lights, sound and light alarm.
There are red/blue lines, red/black lines, red/yellow lines, random delivery (red positive black negative, or red positive blue negative, red positive yellow negative)
Laser diode parameters:
Name: Laser small bronze head (red)
Transmit power: 150mW
Standard size: Φ6 * 10.5
Spot mode: point-like spot, continuous output
Laser wavelength: 650nm (red)
Optical power: <5mW
Supply voltage: 3VDC
Working current: <25mA
Spot size: 15 meters at the spot for φ10mm ~ φ15mm
Mainly for laser toys, various level meter, instrument and other ground
Tips: This laser is a low-power laser, and a small flashlight laser tube, as part of the safety laser.But laser harmful to the eyes, please do not aim at eyes.
Wiring:
The receiving end:
4P green terminal:
The first pin connections: battery box red line, the buzzer anode (long pin), light emitting diode anode (long pin), photoresistor a pin.
The second pin connections: Buzzer another pin, a light emitting diode cathode (short pin), the transistor first pin.
The third pin connections: photoresistor another pin, pin a second transistor, the potential for a single side of the pin.
The fourth pin connections: battery box black wire (ground), the third prong transistors, potentiometers two pins on one side of any one pin.
The transmitter end:
Laser head red wire to the battery box red line, the laser head in addition wire to the battery box black wire. Joints can be used to trap heat shrink tubing, then heated slightly to prevent short circuits.
Ohm's law: U = I * R
