<p>A revolution counter for wrist exerciser includes a generator module, at least a revolution detection element pair, a wireless transmission module, and wireless receiver 50. The generator module, the detection elements, and the wireless transmission module are arranged between a rotor and a stationary casing of the wrist exerciser. The rotation of the rotor with respect to the casing induces a voltage in the generator module, which is supplied to the detection elements and the wireless transmission module. The detection elements detect the rotation of the rotor and generate a signal associated with data of the rotation to the wireless transmission module. The wireless transmission module converts the signal into corresponding data and transmits the data in a wireless manner. The wireless receiver 50 receives the data and displays the data in a display device or transmits the data to an external electronic device.</p> |
