Redundancy

Hi guys,
I would appreciate it if you could please read these two paragraph, and tell me if there are any redundancy or lack of fluency in those:
Thank you

Back in the 1980's PC's and Mainframes began to dominate the world, but today, smart phones and tablets have changed the world. The innovation in technologies leads to creating new devices and development in regular devices. By advancements in electronics electronic parts become smaller, faster, more economic, and even it is possible now that we manufacture gyroscopes, accelerometer, and many other mechanical parts in the size of electronic chips, which they are called Micro-Electro Mechanical Systems or MEMS. These devices enabled us to manufacture devices with various sensors which could acquire data from the environment, and thank to faster processors present better analysis, and more sophisticated functions. For instance, some of them are able to connect to air quality sensors or they can even monitor one's sleep, so they wake up the person in a right sleep phase. Needless to say, they are designed to do a certain job, not like a personal computer, but to interact with other things, and function autonomously.

Cameras and microphones are classic sensors to get information from an environment, however, the data are usually taken to a distance station to analyze. Nowadays, we can produce varieties of modules which usually contain a processor unit, a program, and more importantly a set of sensors to collect data from the environment or an object, and the analysis on the data could be performed both locally and remotely. These module could be part of a bigger system, like adding to a car, as an option, or be placed individually, like a motion detector. There is no need to say that, these modules helps humans and machine to function faster and more efficient; therefore, naturally, they widely use in almost everywhere. “Ubiquitous Sensors” is the name associated with the concept of understanding the environment electronically, and widely with sets of sensors; As for analyzing data, there is “Ubiquitous Computing”, also known as ubicomp, which is an expression to address analyzing, and working toward the acquired data locally, remotely, or both. First off, we will explain how widely Ubiquitous Sensors are used, and how they affected or will affect human life, and then we focus on ubicomp, and how information technology would help to process the acquired data by Ubiquitous Sensors.
