Always-on monitoring for security & safety
Monnit’s Wireless Tilt Detection Sensor tracks the position (pitch) of access barriers, heavy equipment arms, and crucial machinery. With a measurement range of 0–180° and accuracy of 0.5°, this sensor instantly reports (in degrees) when movement exceeds preset limits. If an arm is breached, the tilt detect sensor sends an alert via text, email, or call.
The sensor can also identify if an arm is raising/lowering slowly, indicating seizing hydraulics or motors. This capability helps prevent loss or injury in commercial real estate, agriculture, oil exploration, and other sectors.
The Tilt Detection Sensor is a digital, low-power, low-profile, MEMS based sensor that detects changes in tilt on a single axis and reports data in the form of pitch, based on user configurable orientation changes. The sensor also reports rise/fall time and the current sensor orientation/trigger state.
Simplicity for Safety’s Sake
The Tilt Detection Sensor constantly monitors a single axis of rotation over a range of -179.9° to +180.0°. The data is displayed in degrees with 0.1° of resolution. If the sensor does not experience a detectable orientation change, the sensor will report the most recent measured data at a specified user specified time interval. If a user specified orientation change is detected, the sensor will report immediately.
The sensor has two main modes of operation which determine what triggers the sensor to report. In Up/Down mode user configurable angles are used to define regions for “Up”, “Down”, and “Stuck”. Data is reported when the sensor moves between these regions. In Delta mode the sensor triggers when the absolute difference between the current sensor angle and the last reported angle exceeds a user defined Delta Value. The axis or rotation is user selectable. The axis image below indicates the axis of rotation and the arrow indicates the direction of increasing pitch angle (0° to 180° ▶ -180° to -0°).
Example Data: Pitch: 18.21°, Rise/Fall Time:0 ms, Data State: down
