Sketching

I need someone to draw good sketch of a sensor . A sensor that will be in car passenger seat ? and labelled with how it can detect passengers weight , height and deploy the airbag with the required force depending on persons weight , height. Maybe small drawing not too detailed just maybe small pictures from different angles showing how this sensor have this button and how it does this and that and the material of the sensor just labelling all that as well. Pencil sketch not CAD nothing.
