Develop a detection sensor

Sensor Detect object in a CAR glove box. Looking for a solution for sensing if there is somthing in CAR glove box. Prefered a developer that have specific experiance with a suitble sensor to this chalenge or develop a similar solution. The sensor can be proximity,light sensor,ultrasonic,IR ,IR camera.(IR Infrared Obstacle Avoidance Sensor Module,IR Sensor Obstacle Avoidance Infrared Sensor / Proximity switch 3-80CM,UVM-30A UV,TCRT5000 IR Infrared Line Track Follower Sensor) The sensor should detect any object in any place of the box ,for example glove,tishu,sun glasses,lincense papare and small paper. Its not important to detect the size or distance or what is the object. Any micro or evaluation board of the shelf can be(arduino ,esp,Ti,Atmel) but should be as small as [login to view URL] size 3x3 centimeters. Requirement : Its not important the size or distance or what is the object,however must detect any object. Exist or not exist object in box. minimum size of object is small note paper 6x6 . Location of sensor :one place inside the box. Work in dark inside the box. Target BOM price 5$. Board wakes up every hour and detect if there is or there is nothing in BOX. Retern 1 or 0. Or even get a picture inside the BOX. Have to suggest the sensor and prelimenary EVB board and the estimation for development. If anychange fom requirement then please explain. Source code and all info with be supplied.
