GY-45-52 MMA8452 module - digital triaxial accelerometer modules - inclination module

Detaljan Opis:

• MMA8452 module, high-precision tilt sensor module
• Module Model: GY-45-52
• Power supply :3-5v (the communication is fully compatible with the the 5v system of work)
• Module size L * W = 14.5mm * 20.5 mm

MMA8452Q is a smart low-power 12-bit resolution, three-axis, capacitive micromachined acceleration sensor. 

This acceleration sensor with rich embedded functions with flexible user programmable options, you can configure up to two interrupt pin. Embedded interrupt functions can save the overall power consumption, and to relieve the main processor constantly polling data burden. 

MMA8452Q has ± 2g / ± 4g / ± 8g of user selectable range, the output of the high-pass filter data and non-filtered data in real-time. 

The device can be configured to use any combination of the configurable embedded functions generate inertial wake-up interrupt signal, which makes the MMA8452Q to monitor events at the same time, to maintain a low-power mode in the stationary state.
