Gadget Freak Case #212: Solar Up-Converter Handles Remote Sensors

William Grill's gadget can take energy from an alternate source (such as the sun) and increase the voltage to make the power useful in a wide range of applications.

William Grill has created a solar-based up-converter that can process remote sensors wirelessly. The gadget can take relatively low-voltage energy from an alternate source, such as solar energy, and increase the voltage to make it useful in a wide variety of applications.

Grill began with a handful of items, like inexpensive solar yard lights, and the Harbor Freight IR sensor system. He created the up-converter by tearing these products apart and adding a handful of electronic components.

The wireless remote sensor monitor detects movement at the end of William Grill's driveway and sends a sound signal to a unit inside his house.

The power constraints and issues with the up-converter could be adapted for use with:

  • Wireless remote weather stations
  • Well or hot tub water level monitors
  • Garage door and gate latch/control solenoids
  • Any number of wireless temperature, humidity, or other monitors
