Hi folks,
I am in need some advice.... I am looking for a faster replacement to the following IR sensor unit and would like to know what the people on arduino.cc have seen or heard about?
I am currently using a Sharp GP2Y0A02YK0F Distance Measuring Sensor Unit (http://www.sharpsme.com/download/gp2y0a02yk-epdf) as an infrared trap. Basically if the distance to an object becomes significantly closer than before, do something fun.
Now this analog unit has a range of 20cm to 150cm (7.87 inches to 59.05 inches) and a response time of 39 ms.
The ideal unit will have a quicker response time and if possible, a bigger range. Sharp do offer a number of other units (http://www.sharpsme.com/optoelectronics/sensors/distance-measuring-sensors), but the minimum range is around a meter (3.3 feet) or digital, which doesn't meet my needs.
Have any of you seen similar products with a bigger range and a faster response time, or even a better way to make this trap? Lets assume for the time being that I have a budget of $100+.
