The present invention provides an alarm apparatus comprising at least one sensor including a transceiver. The sensor may be positioned on or attached to a vehicle's fuel filler cap. A collar fitted to an internal face of the fuel cap is associated with a housing for the sensor and a battery, wherein the housing, collar and an O-ring form a watertight seal. The invention further comprises an alert and a control means that is integrated within, and powered by the vehicle. The sensor or one of a plurality of sensors may be provided in the fuel tank. The sensor may be of a type which detects motion or checks the fuel tank contents and/or fuel quality. The control means for the alarm apparatus may be housed on the dashboard. The wiring (see fig 3) includes means for measuring battery voltage. The invention is aimed at providing an effective fuel theft alarm with a low likelihood of providing false alarms. |
