The use of solar cells to drive sensors with optical pumping using readily available laser sources over kilometer lengths is proposed. A simple evaluation finds near IR transmission around 1000-1070 nm is optimal. As proof of principle, we demonstrate a simple humidity sensor powered by solar cell through a 2 km optical fibre link using the 1057 nm output of a Nd:YLF solid state laser. © 2012 SPIE.
