ADXL335 is an integrated, compact, ultra; low power, 3-axis MEMS accelerometer with signal conditioned voltage output. This breakout board for analogue devices is used for sensing motion and accelerometers using I2c or SPI communication. This 3 axis accelerometer measures dynamic acceleration (motion, shock, or vibration) and static acceleration (tilt or gravity). Meanwhile, the ADXL335 Accelerometer Module requires no external devices and works on a 5V power supply. It can be directly interfaced to the ADC of a microcontroller without any external components. ADXL335 was designed with extremely low noise and power consumption of only 320uA used to sense motion or tilt(in case of non-moving) in 3 axes.
The MEMS (Micro Electrical Mechanical System) consists of a micromachined structure made of the silicon wafer suspended freely, which allows it to deflect in any direction when subject to acceleration. Thus, the deflection cause change in capacitance between plates and structure. Hence the change in deflection on each axis is measured as the output voltage proportional to acceleration on that axis. In order to interface with different devices of microcontrollers, a MOSFET based voltage level circuitry is used this module can sense with a full-scale sensing range of ±3 g. The compact size (1″ x 1″) of the breakout board makes it easy to mount the accelerometer to an existing system without the need for additional hardware. As a result, provides a minimal effect on the performance of the system and of the accelerometer.
