Spring 2016 3 DOT Goliath IR Emitter/Receiver Test
By: : Tae Min Lee (Missions, Systems, and Testing Engineer)
IR Mid-Range Proximity Sensor
Implementing a game of laser tag using IR emitter/receiver will be safe for to play for all ages. This falls back to one of our level 1 requirements for safety standards for child safe toys. The figure above shows the connections for the sensor for the following:
- Output
- Ground
- Vcc
Components Used:
- Arudino Uno
- IR LED (Remote Control)
- x3 Red LED
- BreadBoard
- Wiring Kit
- x2 220 ohm resistor
The affective distance of the detector and the IR LED was measured to be around 1.85 meters. The distance was determined by using a remote control that has a IR LED emitter that was aimed at the sensor. We had a red LED to detect when the IR sensor gets hit by the remote control. The laser tag game will have a rule for the first 3 hits will declare the winner (figure seen below).
