Abstract
A sensing device, apparatus and system, and method for operating the same are provided. The sensing apparatus includes a first module and a second module. The first module includes a controller, a transmitter and an array of sensor elements. The controller is capable of activating one or more sensor elements in the array independently of others in the array, in order to obtain a sensor output from the array at different times by using different sensor elements in said array. The transmitter is configured to transmit sensor data derived from the sensor output from the first module to a receiver of the second module. Each sensor element is a biological sensor for detecting the presence of the same analyte in the environment in which the sensor array is to be deployed.
