This Basic Gen 2 900MHz wireless voltage sensor is capable of measuring the voltage between two electrical points. The sensors are capable of measuring voltage by connecting the leads on the sensor to the positive and ground terminals of the device being measured. The sensors can be connected to any kind of variable voltage device, such as a transducer or sensor that outputs voltage. If the device to be measured is passive, the user must supply their own excitation voltage to the device.


  • 900MHz Operating Frequency
  • Wireless range of 1,200+ feet through 12+ walls *
  • Can store up to 3200 readings
  • Frequency-Hopping Spread Spectrum (FHSS)
