To conserve battery power, many devices are kept “asleep” or turned off until the time is right for them to operate. When the device is removed from its enclosure, a sensor is used to trigger its “wake-up.” In this brief video, this function is explained and demonstrated using a RedRock® TMR magnetic sensor within a medical pill camera device which requires the sensor to be tiny, highly sensitive and able to operate within a hermetically-sealed environment while using nearly zero power.
