Alarm Shock Sensor Views
The problem with this design is that all shocks or vibrations close the circuit in the same way. The brain has no way of measuring the intensity of the jolt, which results in a lot of false alarms. More-advanced sensors send different information depending on how severe the shock is. The design shown below, patented by Randall Woods in 2000, is a good example of this sort of sensor.
If the sensor experiences a more severe shock, the ball rolls a greater distance, passing over more of the smaller electrical contacts before it comes to a stop. When this happens, the brain receives short bursts of current from all of the individual circuits. Based on how many bursts it receives and how long they last, the brain can determine the severity of the shock. For very small shifts, where the ball only rolls from one contact to the next one, the brain might not trigger the alarm at all. For slightly larger shifts -- from somebody bumping into the car, for example -- it may give a warning sign: a tap of the horn and a flash of the headlights. When the ball rolls a good distance, the brain turns on the siren full blast.
You should mount your shock sensor relatively close to the center of your vehicle (under the dash is good), so it can detect shocks away from front and back equally well. When you adjust your shock sensor's sensitivity, apply impact from all sides of the vehicle. Keep in mind that an extremely sensitive setting yields the most false alarms. That's true of any sensor.
