Conventional mobile electronic devices have a room for improvement in control on a plurality of sensors to detect information. For example, a mobile electronic device 1 includes a plurality of sensors, a detector that detects a biological reaction by one of the sensors, and at least one controller 10 that performs control to change a detection cycle of other sensors according to whether the biological reaction is detected. For example, the controller 10 changes the detection cycle used when the biological reaction is detected to a detection cycle shorter than the detection cycle used when no biological reaction is detected.
