How to read picamera hardware information that which type of camera sensor(imx219 or OV5647) is being used in camera mod

I want to read the camera hardware spec to ensure which type camera sensor (like imx219 or OV5647) is being used in the rPi camera module for camera module v1 & v2.

Is there any method to read that hardware information from the camera module?
