Tamper Detector
Was I Bumped? If So, How Hard?
Hummingbird Electronics manufactures a range of rugged, calibration-free electronic tamper detectors. Tamper detectors are typically used to sound an alarm when a stationary vehicle is moved without the ignition being turned on.
Powerful Performance
Designed for harsh automotive environments, the modules feature transient voltage protection on the supply and short circuit protected outputs.
Tamper detectors measure small variations in tilt, height or position typically associated with movement.
Two outputs are provided for varying sensitivity. Upon detecting a variance exceeding the low threshold, a normally low output will go high. A second output will go high if forces exceeding the high thresold are detected.
The tamper detector would typically be connected to a relay which would drive a buzzer or light as a warning to the driver.
Tamper detectors are available with high current outputs to allow direct connection to a relay or other device.
When power is applied, the red light will light whilst the unit is performing self-test and calibration activities – this will typically last for 15 seconds.

Rugged Hardware
The tamper detector is supplied in a rugged ABS plastic enclosure that is completely waterproof. Provision for screw mounting when required is provided.
Power to the unit and switch outputs are provided through colour coded wires.
