some cameras (usually more expensive ones) have better filters that block IR

water pumps and garage doors

home switches

It also includes an energy harvesting pin capable of outputting µW of power with an RF field of sufficient strength

but high-reflectance objects are generally detectable out to around 40 mm

Mini Power Meter with Voltage, Current, Watts, mAh & mWh Display SF_3-axis some cameras (usually more expensiveThis Mini Power Meter with Voltage, Current, Watts, mAh & mWh Display (whew that is a mouth full) is a lot like the USB In Line Voltage and Current Meter we carry but can be used with a wide range of voltages ( not just USB connections). Measure the working voltage and current output for any project with this really fancy power meter. This power meter has a small LCD display that shows off voltage, watts, amps, and mAH and instantly reads the numbers
