An electronic device may include a position detecting unit that detects a position; a time detecting unit that detects a time; a communicating unit that communicates with a first device provided separately from the position detecting unit and the time detecting unit; and an instructing unit that instructs, via the communicating unit, a first detecting unit provided to the first device to perform detection according to a detection result of the position detecting unit and the time detecting unit. An electronic device may include a position detecting unit that detects a position; a time detecting unit that detects a time; a physical amount detecting unit that detects a physical amount of an ambient environment according to a detection result of the position detecting unit and the time detecting unit; and a human detecting that performs detection about human according to a detection result of the physical amount detecting unit.
