Does any body know the name of this sensor? ​

Explanation:

here a similar pic to it .i hope this helps :)

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !

make sure each item is its own paragraph.
