Tilt-Switch
When Falling Over Is Not An Option
Hummingbird Electronics manufactures a range of rugged, calibration-free electronic tilt-switches. The tilt-switches can be used to trigger an event upon a certain angle being achieved. Pre-set and user-settable versions are available, as single axis (horizontal only) or dual axis (pitch and roll) sense versions.
Powerful Performance
Designed for harsh automotive environments, the module features transient voltage protection on the supply and short circuit protected outputs.
The tilt-switch is designed to provide a signal to an external system or to drive an external relay upon a pre-set or user-settable angle being achieved. At this angle, normally low (0V) outputs go high (Vin). In the user-settable version, a multi turn pot is provided to set the desired trigger angle. When turned fully anti-clockwise, an alarm angle of 0 degrees will be set, and when turned fully clockwise a trigger angle of 90 degrees will be set. A red LED gives a visual confirmation when the unit is triggered. Once triggered, the switch will remain on until the tilt angle is reduced below the threshold. The switch is available in either a single axis or dual axis version. The dual axis version differentiates between pitch and roll and will trigger independent outputs as the trigger angle is detected.
Tilt-sensors provide a 0V to 10V output, depending on tilt angle. At 0 degrees (horizontal), 0V will be produced and at 90 degrees, 10V will be produced. As standard, a tilt to the left or right (and front / back) are treated equal and will produce an increase in voltage. Units which differentiate between tilt to the left and right (and front / back) are available on request.
