The remote sensing examples shown here feature high reliability, easy connectivity, and very low power. These circuits target industrial settings that require robust communications and minimal battery maintenance. The solutions combine recent advances in low power, high precision amplification with comparably low power, high reliability wireless mesh network capability.

Enabling the solutions are the LTC2063 zero-drift, low input bias amplifier, which runs at 2 µA max, and the LTP5901-IPM, which consumes less than 1.5 µA in sleep mode. The power dissipation for these devices is low enough that they can run from a benchtop-made battery comprised of copper and zinc electrodes, each four inches square in area, and an electrolyte consisting of the pithy innards of a lemon (more info).
