A device may include a wireless communication interface configured to communicate with a sensor reading device, receive a wake up command from the sensor reading device, and receive reflected energy from a sensor. The device may also include one or more processors, and one or more non-transitory computer readable media including instructions that, when executed by the one or more processors, perform or control performance of operations. The operations may include performing a wake up operation based on the wake up command from the sensor reading device, and recording the reflected energy from the sensor. The operations may further include generating a report regarding the reflected energy, and causing the wireless communication interface to transmit the report to the sensor reading device.
