The MikroE TILT-n-SHAKE Click Board™ is a multifunctional add-on board that is designed to keep away people from tampering with your design. Featuring a combination of tilt AND shake functionalities, the TILT-n-SHAKE Click Board™ includes an MMA8491Q IC sensor that is used as a 3-axis, 45-degree tilt sensor and can also be configured as a 3-axis digital accelerometer. The user is required to keep the Enable pin (EN) pulled to logic level high to use it as an accelerometer.
Featuring a 14-bit digital output and 8g full-scale range, this MEMS chip has a 1 mg/LSB sensitivity, and a fast response time of around 700 microseconds. TILT-n-SHAKE Click Board™ communicates with the target board MCU through MikroBUS I2C interface, using SCL, SDA pins. As a tilt sensor, the MMA8491Q chip has three detection outputs, one for each axis: Xout, Yout and Zout. For specific applications, you may need only one or two dimensions, not all three.
This Click Board™ is intended to use a 3.3V power supply. It is ideal for tamper detection and anti-theft detection systems.
