It is described a very low cost system for automatic data acquisition consisting of a conventional photogate activated by infrared light, and a digital stopwatch with 0,01 s of resolution with the start/stop functions triggered by the photogate. The system is designed to determine time intervals and is intended for use in both first year undergraduate physics courses and in high school experimental physics laboratories.
