Spynet Laser Trip Wire

Product Information

The Daytripper transmitter uses a laser time-of-flight sensor, in this case the very small VL53L0X by STMicroelectronics.

It has built-in support for minimizing all windows or locking the computer, or you can set it to send ALT + Pause, which you can listen for and act on however you see fit. It was received by an LDR connected to a video game controller button, so a PC could sense it (before I knew about microcontrolers). The LED will light and the Audible alarm will sound if the beam is broken, whether that be intentionally or potentially spiritual or paranormal activity if there is no human presence near the device when it triggers. This step is optional, but I chose to give the pins descriptive names so they are easy to remember and track.Although I want to be able to turn the laser on/off, the Digital Output pins on the Arduino do not provide enough power for my laser diode. First of all, try to place the sender and receiver units at the top of the stairs with a slight distance between them.

This is because they are regularly used in high-security settings such as military bases and government buildings. Ethernet cable is included with every sensor – it has to be connected to the Universal puzzle controller to work.There are 3 parts of the circuit: the laser power, the photoresistor receiver (the sensor), and the LED indicator (the actuator). If a person "trips" the wire, the emitter will sense that an entity is blocking the laser, and it will trigger some form of consequence, such as drawing guards and bots to the location, or releasing poisonous gas. Also, if I ever change how the circuit is wired I only have to change the Pin Definition as opposed to changing every line of code where the pin number is mentioned. The red line laser actually triggers a latching switch, that can be connected to any external load/security device such as a loudspeaker alarm, floodlight, or CCTV cameras.
