Claim 8:
9. The sensor assembly of claim 8, further comprising:
a second SAW sensor adapted to measure the first environmental condition responsive to receiving the first RF signal or a second RF signal, the second SAW sensor comprising a second IDT formed on the piezoelectric material of the first substrate or on a second substrate; and
a second dielectric coating of at least one of a second thickness or a second material disposed on the second IDT, wherein:
the second IDT comprises the first base resonant frequency or a second base resonant frequency;
at least one of the second thickness or the second material is associated with a second shift in the second base resonant frequency; and
the second IDT with the second dielectric coating has a second adjusted resonant frequency.
