EasySens - The progressive radio sensor system (12/11/2004)

For the first time, the building control technique is experiencing a comprehensive product line of sensors and receivers making it possible to build up wire-less and maintenance-free sensors within buildings. This significant progress has been enabled by means of EasySens.

By integrating innovative, solar-powered radio transmission technique in Thermokon sensors, the devices are operating without batteries. Due to the maintenance-free operation and radio transmission, the sensors are practically working at any place.

At the moment, various devices for temperature control, relative humidity, set point adjustment and status detection are available. Of course, the current product range will be extended in future, so to offer a complete programme for other applications, as well.

High-frequency emission of radio sensors

Since the development of cordless telephones and the use of radio systems in residential buildings, the influence of radio waves on people's health living and working in the building has been discussed intensively. Due to missing measuring results and long-term studies, feelings of uncertainty have existed with the supporters as well as with the critics of radio systems.

A measuring experts certificate of the institute for social ecological research and education (ECOLOG) has now certified, that the high-frequency emissions of radio keys and sensors based on the EnOcean technology are considerably lower than with comparable conventional keys.

Thus, it is good to know, that conventional keys also send electromagnetic fields, due to the contact spark. The emitted power flux density (W/m") is 100 times higher than with radio sensors when looking at the total frequency range. In addition, a potential exposition by low-frequency magnet fields, emitted by the wires, is reduced due to wireless radio keys. If the radio emission is compared to other high-frequency sources in a building, such as DECT-telephones and base stations, these systems are 1500 times higher-graded than radio keys.
