The MPU-6050 is the world’s first and only 6-axis MotionTracking devices designed for the low power, low cost, and high performance requirements of smartphones, tablets and wearable sensors.By combining a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor(DMP) capable of processing complex 9-axis MotionFusion algorithms.

The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor.For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

HC-SR04 Ultrasonic ModuleDistance Measuring Transducer Sensor for arduino. 

This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately.

The module is with High precision, blind spots (3cm) super close.

This module provides a full set of ranging process.


As any ultrasound sensor, the HC-SR04 operates like a simple radar, by sending a series of pulse waves and listen to an echo.

To measure a distance, start by sending a short trigger pulse to the TRIG pin, at the same time monitor the ECHO pin until the output is HIGH and measure the pulse width.

The distance is equal to (pulse duration in seconds) * (speed of sound) / 2 where the pulse width is in unit of second and sound speed is in unit of meter/second.

Normally sound speed is 340m/s under room temperature.

To use this sensor with the Arduino simply download the srf04-library if you're using the Arduino IDE 1.0 or theUltrasound Library if your IDE version is older.

We recommend a pause of 60-100ms between each distance reading to allow the echo pulse enough time to settle.
