Description

The wireless photogate can be used to measure: timing, velocity and distance, when combined with the (included) smart pulley.

The photogate is switched on and off using the power button. It has a color OLED colour display that shows sensor information, measured values, and the selected mode, allowing it to be used as a standalone measuring instrument. Press the button to turn it on, and hold it for about 5 seconds to turn it off.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 Lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).

Technical specifications of the photogate sensor are described in the product manual, see downloads.

The wireless photogate can be used for a wide variety of physics experiments:

Measuring the acceleration due to gravity (use a transparent piece of plastic with stripes at regular intervals, which can be allowed to fall through the photogate),
Motion measurements using a Smart Pulley
Measuring the speed and acceleration of moving objects
Measuring time intervals of moving objects
Measuring the period of a simple pendulum
Studying rotational motion and its period.
