SQ-PTS PROGRAMMABLE MEMS TILT SWITCH ±70 º DUAL AXIS, 360 º SINGLE AXIS, DIGITAL OUTPUT DESCRIPTION The tilt sensor module provides a digital level output if pre-programmed angle thresholds are exceeded. The two standard digital outputs can be configured at the factory as two different angle thresholds. In addition 4 additional input/output lines can be factory configured for a variety of functions on a semi-custom basis, greatly simplifying designs that require accurate, reliable angle detection. THEORY OF OPERATION The inclinometer uses 2 factory calibrated accelerometers to measure and compute angles made between its axes, and the gravity vector. The trigonometric conversions between acceleration and angle are made by an onboard processor. Additional processing filters spurious acceleration and vibrations to reduce the impact on the resulting output angle. ± 70 º dual axis angle measurement 360 º single axis angle measurement ± 1 º accuracy 0.10 º resolution Configurable trigger angles Configurable hysteresis (Schmitt trigger) for debounce Configurable reset and trigger delay Configurable filtering and bandwidth Low temperature drift High reliability solid-state MEMS Digital filtration for stable measurement Reliable on/off tilt switching Machine control 10 Water St. Lebanon, NH 03766 USA Page 1 of 11 www.signalquest.com info@signalquest.com

SQ-PTS PROGRAMMABLE MEMS TILT SWITCH ±70 º DUAL AXIS, 360 º SINGLE AXIS, DIGITAL OUTPUT Since the device is a subassembly of surface mount components, it is not suitable for automatic assembly or wave soldering. Hand soldering of pins or SMT pads is specified for 3 seconds at 218 ºC. Pins labeled NC (no connect) should be soldered to open connection pads / pins for mechanical stability. The designer should test the device’s output voltage through its entire desired angle range during prototyping to ensure that it is working properly in the application. The device can be mounted vertically...
