Claim:
1. A Baby Monitoring Mat, comprising: a sensor mat having a top mesh layer, a bottom mesh layer, and two flexible sheets and an optical cable, wherein the optical cable is routed across and sandwiched in between the top mesh layer and the bottom mesh layer, and the flexible sheets further sandwiched the top mesh layer and the bottom mesh layer in between forming sensing area across the flexible sheet surface; a light source for feeding light from one side of the optical cable; wherein the light source is a light emitting diode; a photodiode for detecting light attenuation at the other end of the optical cable; a printed circuit board having a processor connected to the light source and the photodiode, wherein the processor operationally receives signals from the photodiode, the signals are processed to determine movements and breath counts, wherein the signals are generated based on the light attenuation changes along the optical cable detected by photodiode, the light attenuation changes are operationally caused by the optical cable bending in response to the movements and breath.
