PROBLEM TO BE SOLVED: To provide a rotation detection device of an air blower capable of setting an changing, easily on the field, the difference of a rotation speed, the number of blades, an output form or the like, and easily confirming the changed content, by using single hardware and software. SOLUTION: The main measuring operation for rotation detection is performed by the software by using a microcomputer, and the difference resulting from the difference of a specification of this air blower or the difference of the output form of the rotation detection is supplemented by the hardware such as existence of jumper cable connection and switching of a switch, or either of both means.
