Typical application – Wireless sensor system with Time Code Reception
The system in figure 7 shows a wireless module that can receive both the AM long wave Time Code Signal as
well as measuring different physical parameters via several sensors. The information is transmitted via a low
power RF transmitter to a receiver indoors. By placing the module where the Time Code signal is strong good
reception can be accomplished also in buildings normally blocking this signal. The low power consumption of
the MAS6011 together with the energy harvesting solar cell enables this system to operate without the need for
battery replacement.
