Essential Info

Do you have a need to know when vehicles enter your driveway? This sensor is designed to be buried 6" to 12" deep and uses changes in the earth's magnetic field to detect when vehicles pass over. Note this is not a presence detector but a motion detector - vehicles must be moving 5 mph or more in order to be detected. Its sensitivity is adjustable in 10 steps with a remote sensitivity adjustor (sold separately) to customize for your traffic pattern. The detector's non-volatile memory retains the setting so the remote may be removed, thus reducing power consumption. This also prevents unwanted changes to your settings. At maximum sensitivity it has a 12' detection range, depending on vehicle mass and speed. A green LED indicates power on, and the device can accommodate voltages between 9 to 41VDC or 6 to 29VAC. The output is a SPDT form C relay. This sensor is also available with a 50 foot cable, sold separately.


What's Included

  • 1x - Driveway Sensor with Adjustable Sensitivity
  • 1x - Wiring Harness for Remote Sensitivity Adjustor (Adjustor Sold Separately)
  • 1x - Instruction Manual
  • More Info

    The VMD202 is a compact vehicle motion detector that operates by detecting changes in the earth's magnetic field that occur near the probe. These changes are produced by the movement of ferrous materials such as cars or trucks within the probe's range. The VMD202 produces a trigger signal for free exit. The direct burial VMD202 probe is placed adjacent to a roadway or buried in a concrete or asphalt roadway.
