Photogate Sensor

Description:
The photogate sensor is a digital switch sensor, with the infrared emitter and infrared receiver at both ends respectively. Under a normal working condition, the infrared emitter sends the infrared beam to the infrared receiver consistently, when the infrared receiver receives the optical signal, it will be converted into an electrical signal. If the infrared receiver receives the light beam, the photogate sensor will be below (open situation); if the infrared beam is blocked off, and the infrared receiver fails to receive the beam, the photogate sensor will be high (closing situation). The photogate sensor can be used to measure the time consumed by one event or a series of events. If the regular light barrier is used, and the size of the light barrier is known well, when the light barrier passes through the beam, the system will calculate the speed; if two photogate sensors are used, or dual-light barrier is used, it can also calculate the accelerate by same way.

Typical Experiment:
Measure average speed.
Explore Momentum Theorem.
Test Law of Conservation of Mechanical Energy.
Measuring the speed of objects undergoing collisions.
