Pololu MinIMU-9 v5 Gyro, Accelerometer, and Compass (LSM6DS33 and LIS3MDL Carrier)

The Pololu MinIMU-9 v5 is an inertial measurement unit (IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny 0.8″ × 0.5″ board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v5 board includes a voltage regulator and a level-shifting circuit that allow operation from 2.5 to 5.5 Volt.

SparkFun Triple Axis Magnetometer – HMC5883L

This is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied. The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low-cost compassing and magnetometry. Applications for the HMC5883L include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices.

Sensor

A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.

  • Acoustic, sound, vibration
  • Automotive
  • Chemical
  • Electric current, electric potential, magnetic, radio
  • Environment, weather, moisture, humidity
  • Flow, fluid velocity
  • Ionizing radiation, subatomic particles
  • Navigation instruments
  • Position, angle, displacement, distance, speed, acceleration
  • Optical, light, imaging, photon
  • Pressure
  • Force, density, level
  • Thermal, heat, temperature
  • Proximity, presence
  • Sensor technology
  • Speed sensor
  • Others
  • Etc…

SparkFun Triple Axis Accelerometer Breakout – ADXL335

Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors, the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption.
