Abstract
This system is directed to a batteryless, self-powered sensor comprising: a microprocessor; a first and second solar panel in electronic communications with the microprocessor; a transceiver in communication with the microprocessor; and a set of computer readable instructions included in the microprocessor adapted for creating motion data including a direction and a speed of movement of object within a first sensing area and a second sensing area, transmitted the motion data to a remote location if sufficient power is provided by the first solar panel to actuate the transceiver and a number of data points in the motion data exceeds a pre-determined number of minimal data points, associating a reduction in power delivered from the first solar panel to the microprocessor with movement and associating an increase in power delivered from the first solar panel to the microprocessor with movement.
