PROBLEM TO BE SOLVED: To provide an information measurement device capable of detecting, at a reception side, that a voltage of a secondary battery at a transmission side becomes equal to or lower than a predetermined voltage and the voltage is recovered thereafter, an electronic apparatus, an information measurement method and a control method for the electronic apparatus.SOLUTION: The information measurement device is configured to communicate with the electronic apparatus and comprises: a first communication part that communicates with the electronic apparatus; a power generation element; a secondary battery that is charged with power generated by the power generation element; a first storage part storing charge/discharge properties of the secondary battery therein; a voltage detection part which detects a voltage value of the secondary battery; and a first control part which calculates the lapse of time in the case where discharge is started in a full charge state of the secondary battery, based on the detected voltage value of the secondary battery and the charge/discharge properties being stored in the first storage part and performs control in such a manner that information indicating the calculated lapse of time is transmitted from the first communication part to the electronic apparatus.SELECTED DRAWING: Figure 1 |
