Spanish scientists are revolutionizing the market for smart meters with wireless sensors that have hardware and software itself. The sensors have a guaranteed energy supply through photovoltaic microelements. The device reduces the cost barriers to deploying advanced sensors in buildings to enable optimization of energy usage.
The wireless sensor is networked and scalable, consumes very little power, is software programmable, capable of fast data acquisition, reliable and accurate over the long term, costs little to purchase and install, and requires no real maintenance. Take measures of Temperature and Relative Humidity every 60 seconds.
The source of energy is a PV micro cell that provides a microprocessor with electricity. The mean intensity in the microprocessor is 0.06mA. Data are sent without a battery and without any cables. PV microcells are the energy source to the wireless device. Furthermore, the embedded firmware can be upgraded through the wireless network in the field.
