Abstract

This paper proposes a wireless visual sensor comprising of a low-cost grayscale camera as the sensing hardware and a BlueTooth (BT) 100-m slave module as the transmission hardware. The latter enables the sensor to be inserted as a node in a medium-range BT measurement network. The proposed sensor, which is designed to satisfy precise specifications in terms of image-transfer rate and power consumption, represents a good image-acquisition solution in a wide range of applications where hardwiring between camera and image processor is undesired. This paper describes the hardware used and the overall operating principle behind the sensor, discusses the sensor-node performance, and reports the results of reliability tests.
