In this paper is presented a real prototype of ultra-low power battery powered sensor board which is aimed to be the “coin” size device. Prototype squeeze in small size MCU + radio module + sensor capable of measuring temperature, humidity and atmospheric pressure. The realization from schematic to prototype production is described in the article.
