摘要： Provided are a vibration detector and a vibration detecting method, which are power saving, can detect vibration even if the vibration is very weak, and can perform both start-up of the apparatus and collection of data of vibration information by the use of only one sensor. The apparatus includes a vibration detector, a semiconductor switch, a controller and a power supply. The semiconductor switch and the controller are connected to the power supply. The vibration detector detects vibration and consequently generates a vibration voltage. The semiconductor switch includes a voltage divider for generating a bias voltage inside. The semiconductor switch detects a voltage produced by superposing the bias voltage onto the vibration voltage outputted from the vibration detector, and conducts current when the detected voltage is equal to or larger than a certain value. The controller wakes up with the current conducted by the semiconductor switch as a trigger signal.
