Weather resistant, battery operated transmitter notifies receiver when a vehicle enters the protected driveway. It uses a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object close to the driveway sensor will cause the sensor to transmit to the receiver. People, animals and shadows will not trigger the sensor. The sensor operates up to 1000 ft. (line of sight) away from the indoor receiver. It is easy to install and is supervised for low battery and signal reception.
