Freescale have introduced a new range of 3-axis accelerometers offering high sensitivity at low power consumption. According to Freescale the FXLN83xxQ family is capable of detecting acceleration information often missed by less accurate sensors commonly used in consumer products such as smartphones and exercise activity monitors. In conjunction with appropriate software algorithms its improved sensitivity allows the new sensor to be used for equipment fault prognostication (for predictive maintenance), condition monitoring and medical tamper detection applications.

We have already seen a number of ideas for tracking tags seeking funds on Kickstarter, most systems are limited by the range of Bluetooth communication with a smart device. This system from Iotera tackles the problem using cloud-based thinking: The basic wireless system consists of one or more tags or ‘iotas’ and a home base unit. Each 22 x 11 x 3 mm iota contains a chip, accelerometer, temperature sensor, speaker, RF transceiver, Bluetooth (unused so far) and a battery to give up to three months operation. Each iota communicates with the home base unit using wireless channels in the 902 to 928 MHz band giving a range of up to four-miles. Back home, the base unit receives the low-speed transmissions from the iota tag and forwards the information to a server via a Wi-Fi connection.

Designed for high-precision, always-on, six- and nine-axis applications, such as smartphones, tablets, remote controls, and game controllers, the BMI160 inertial measurement unit (IMU) combines a 16-bit, 3-axis, low-g accelerometer and ultra-low-power, 3-axis gyroscope. When the accelerometer and gyroscope are in full operation mode, typical current consumption for Bosch Sensortec’s IMU is 950 µA.

This guide is intended to everyone interested in in using Accelerometers and Gyroscopes as well as combination IMU devices (Inertial Measurement Unit) in their electronics projects
- What does an accelerometer measure?
- What does a gyroscope (aka gyro) measure?
- How to convert analog-to-digital (ADC) readings that you get from these sensor to physical units (those would be g for accelerometer, deg/s for gyroscope)
- How to combine accelerometer and gyroscope readings in order to obtain accurate information about the inclination of your device relative to the ground plane

The accelerometer can measure acceleration in two axis using Analog Devices ADXL202. +-2g can be measured in each axis.
The accelerometer can measure acceleration and time. Using the time and the acceleration it can calculate and display:Time (s)
- Average acceleration (m/s2)
- Instantanous acceleration (min/max) (m/s2)
- Speed (m/s & km/h)
- Distance (m & km)
The mass of the object can also be input, the accelerometer can then also display:Instantenous Force (N)
- Average Force (N)
- Instantenous Power (kW and HP) * .

The team describes it as the world’s first starter-kit designed for App Developers to build apps, for the devices and things around them. A “chocolate bar” with detachable bits of different sensors and Bluetooth Low Energy, connected to a mini wifi base, together with easy-to-use SDKs for iOS, Android, node.js, and our simple REST API.
The WunderBar is the easiest way to create useful connected devices. It works out-of-the-wrapper, contains a host of awesome sensors, and is dead-simple to program.
Sensors include: Light, color, distance, temperature, humidity, remote control (IR), accelerometer, and gyroscope. Two additional sensors will be chosen by you.

This project is an accelerometer data acquisition system for automotive suspension analysis. In other words it’s a low frequency spectrum analyzer based on Lanchpad TIVA Series from Texas Semiconductors. It’ s a spectrum analyzer for mechanical frequencies (max. 50 Hz). In my application I use this analyzer for the signals from a suspension of a car, that contain information about comfort (ride) of a vehicle.

STMicroelectronics have announced the LSM6DB0, the latest addition to its iNEMO family.
It packs a 3-axis accelerometer, 3-axis gyro and low energy ARM-based Cortex processor in a tiny 3 x 3 mm package.
This chip is designed to interface with baseband chipsets that don’t have a sensor co-processor. Additional external sensors can also be hooked up via its I2C interface, allowing the on-board processor to take care of all sensor-related functions to help minimize application latency at a system level. The device is fully compatible with all of the latest mobile operating systems including Android Kit-Kat 4.4. The sensor’s performance is the result of true 6-axis sensing, where both the 3-axis accelerometer and 3-axis gyroscope are manufactured on the same chip. They operate synchronously at the same output data rate,combinig correlated, true six-degree-of-freedom motion and not just separate acceleration and angular-rate inputs. [via]
