Wireless Sensor Networks and MotesWireless sensor network (WSN): a wireless network consisting of spatiallydistributed autonomous devices using sensors to cooperatively monitor physical orenvironmental conditions (e.g. temperature, sound, vibration, pressure, motion orpollutants) at different locations.A Mote is a small piece of something, such as a dust particle. Mote is the nameusually given to WSN boards (mote boards, MB).MemoryExp ConnectorMCU3 ARSLOGICA srlVia Trento, 117 - 38017 Mezzolombardo (TN), Italy - Tel. +39 0461 600253 Fax. +39 0461 603250 Email: [email protected] w w . a r s l o g i c a . i tMote components:Microcontroller (MCU)Radio ChipAntennaPower source (e.g. battery)External MemorySensors (S)Expansion ConnectorMoteRadioChipSSPower(battery) 4.
