Abstract: A voltage detection device for detecting proximity to an active alternating current (AC) voltage source is provided. The device includes a housing, at least one antenna configured to generate a signal in response to exposure to electromagnetic radiation, signal processing circuitry configured to process the signal generated by the at least one antenna, a processing device embedded in the housing and communicatively coupled to the signal processing circuitry, the processing device configured to determine, from the processed signal, whether the voltage detection device is proximate to the active AC voltage source, and an electronic switch embedded in the housing and one of included within the processing device and communicatively coupled to the processing device, the electronic switch configured to reduce an impact of interference on detection of the active AC voltage source.
