Integrated simple pendulum instrument

The invention discloses an integrated simple pendulum instrument. The integrated simple pendulum instrument comprises a digital millisecond meter, a photogate, a light shielding metal sheet and a simple pendulum device. The photogate is electrically connected with the digital millisecond meter. The end part of the light shielding metal sheet is arranged at the top of the simple pendulum device. The photogate is arranged at the upper part of the simple pendulum device and is vertical to the space of the light shielding metal sheet in a vertical state. Through the digital millisecond meter, the time for swinging and shielding the photogate by the light shielding metal sheet is recorded, integrated simple pendulum automatic period record is achieved, simple pendulum experiment record is achieved furthermore, and the technical problems are solved that at present a simple pendulum and a measuring device are not an integrated body, installation is carried out first, then debugging is carried out, thus operation is complex.
