STMicroelectronics, a global semiconductor, is enabling more acoustically comfortable cars, with its new sensor for road-noise cancellation (RNC) through active noise-control (ANC) techniques. Vehicles have traditionally been defined by engine performance, exterior design, and powertrains, but drivers and passengers are increasingly focused on comfort. While electric vehicles (EVs) are intrinsically less noisy than internal combustion…
STMicroelectronics offers multi-connectivity development kit for asset tracking
The STEVAL-ASTRA1B multi-connectivity evaluation platform from STMicroelectronics provides a complete ecosystem for building a complete proof-of-concept for asset tracking systems. Battery-powered, and with a small form factor, the evaluation kit also includes firmware to simplify the development of targeted applications, such as livestock monitoring, fleet management, and logistics. The kit helps users evaluate ST’s industry-first short and…
STMicroelectronics releases first automotive IMU with embedded machine learning
STMicroelectronics’ ASM330LHHX inertial measurement unit (IMU) moves smart driving another step closer to high levels of automation with its machine-learning (ML) core. The ML core enables fast real-time response and sophisticated functions with low system-power demand. Leveraging ST’s micro-electro-mechanical systems (MEMS) technology, the automotive-qualified ASM330LHHX houses a 3-axis accelerometer and 3-axis gyroscope in a 2.5 x 3…
What is sensor fusion?
by Charles Pao, senior marketing specialist, CEVA Motion sensing devices are all around us and in several of the electronics that we use daily. Motion sensors are in earbuds – noticing taps to change songs or pausing music when we take them out of our ears. They’re used for head tracking in virtual reality (VR)…
Interfacing triple-axis accelerometer with AtMega16
This project makes use of three out of the eight ADCs present in AtMega16 IC to display the corresponding digital data of X, Y and Z outputs of an accelerometer on 16X2 LCD.It’s very easy to deal with such kind of modules as they just need the VCC and GND supply to get started, rest it is its job to provide us the analog data.These modules work on simple concept like that of force acting on an object at inclined plane. It deals with the Mg(sin ?) and Mg(cos ?) part of the force and calculate the angle ? for further calculations. Now it also notices the change in force from which acceleration will be calculated.
Accelerometer Controlled Robot without a Microcontroller
You may have come across many tutorials about accelerometer controlled wireless robot (also known as gesture controlled or glove controlled) but all of them would have a microcontroller. This tutorial teaches you how to make them without using any microcontroller.
Accelerometer Based Hand Gesture Controlled Robot
In many application of controlling robotic gadget itbecomes quite hard and complicated when there comes the part of controlling it with remote or many different switches.Mostly in military application, industrial robotics, construction vehicles in civil side, medical application for surgery. In this field it is quite complicated to control the robot or particular machine with remote or switches, sometime the operator may get confused in the switches and button itself, so a new concept is introduced to control the machine with the movement of hand which will simultaneously control the movement of robot.
Introduction to Accelerometer
Want to know how fast your car’s going? It’s easy—just glance at the speedometer!Speed is a handy measurement that tells you how quickly you can get from one place to another. A car’s top speed is generally a good indication of how powerful an engine it has, but assuming everyone stays within the speed limit, maximum speeds are just numbers on paper—little or no use to anyone.
Body in motion usually experience vibration as well as shock. When a mobile falls on a floor, it is subjected to shock. When a vehicle moves on a bumpy road, it experiences vibrations. Likewise, there are many situations, where an object encounters shock and vibrations. Sometimes, they survive and at times, they get damaged. When delicate items like glass, crockery, etc. are packaged properly, they can withstand severe shock and vibrations. Whether a system will survive or not, how do we know this a priori? While some vibrations are desirable, some may be disturbing or even destructive. Hence, often a need is felt to understand the causes of vibrations and to develop methods to measure and prevent them.
Microcontroller Based Accelerometer
1. Introduction: Acceleration is a measure of how quickly speed changes. Just as a speedometer is a meter that measures speed, an accelerometer is a meter that measures acceleration. You can use an accelerometer’s ability to sense acceleration to measure a variety of things that are very useful to electronic and robotics projects and designs: · Acceleration…
Computer Mouse Control By Accelerometer
This project demonstrates the use of a accelerometer as a computer mouse,but first what is an accelerometer? Its a device that can measure acceleration and the pull of gravity.There are multiple ways of doing this, the particular one I’m using works with the capacitive method. Inside the chip is a capacitor with an extra plate in the middle that can move. As you know the closer the objects are together the bigger the capacitance, the circuit inside the chip measures the capacitance difference between the two plates and the middle one.
