Wireless Sensor Network
Formal
Autonomous sensor nodes that are connected to one, or sometimes several, other sensors to cooperatively pass their data through wireless connections to a main location.
Practical
A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions.
