For what kind of sensors does EnOcean technology work?
In principle this is of course a question of the energy balance. Basically EnOcean is suitable for all sensor elements that are only briefly operated. Typical times are 1 millisecond at a current of 2 milliamperes. On a 5 volt supply you then have a total energy need of about 10 microwatt seconds per measurement. This is of the order it takes to send a wireless telegram. A solar cell produces about 20 microwatts at 400 lux, a thermogenerator about 20 microwatts at 5 Kelvin temperature difference. So what is important is the ratio of measurement duration to the number of measurements in time (on/off ratio). Typically the measurement cycles should be in the range of seconds rather than milliseconds.
