A word used in many ways: from the broadest concern, awareness and government legislation over “the environment”, to the desire to control the environment of a room in a building, Low Power RF communications are commonly used.
Wireless sensors can be used to monitor environmental factors such as river levels and atmospheric pollution – the RF link could be to a data logger, perhaps at a water utility company water treatment works.
Other example applications include agriculture (e.g. irrigation control) and indoor environments can use RF communications to provide the feedback and control paths for air conditioning, central heating systems (HVAC) or refrigeration management in supermarkets.
Local authorities may use RF remote control in selective lighting to improve security in an urban environment.
