By the year 2025, advances in the Internet of Things (IoT, including wearable technology) will be very rapid, as is the case with sports watches built with fitness or tracking capabilities that are ubiquitous by that time. It has been predicted that the number of devices connected to the network will grow to 50 billion by 2020.The Internet of Things (IoT) is also wrapped up in a larger network of things (io

Although the concept of "Iot" has been on fire for a whole year, in fact, various operators have already launched many projects in the name of "Industrial Applications. Such as street lamp monitoring, hydrological monitoring, vehicle positioning, Smart Home, and electric power remote meter reading. These services are based on various types of sensors for information collection, using GPRS or SMS as the information transmission channel, and then proces
In the previous article, what are the opportunities to seize the emerging IoT industry tuyere? We present six common types of IoT mobile application development. Today, Apicloud developed the vehicle networking project as an example, the development process of the relevant project experience and communication technology structure!▌ Project IntroductionThe initial charging of new energy car owners only throu
Overview
The origins of relational databases originate from the set concept in mathematics. therefore, the operation between a set and a set also inherits the operation between mathematical sets. in relational databases, it is often used for "relational" in two relational databases that are not directly used, such as foreign keys. however, there is an indirect relationship between the two datasets. For example, there is an indirect relationship betw
Apache Spark provides a powerful API to make it possible for developers to use complex analytics. By introducing Sparksql, developers can use these advanced API interfaces to work with structured data (such as database tables, JSON files), and provide an API for object-oriented use of RDD, and development only needs to invoke related methods to use spark to store and compute data. So what Spark1.6 bring us something? The amount ...SPARK1.6 provides an API for Datesets, which will be a trend for

This article implements the interaction between Arduino and FPGA. Of course, there is no new protocol, or it is based on serial communication. Now, learning a serial communication can basically drive most modules, moreover, it can seamlessly interact with various single-chip microcomputer data. Because of its powerful Library Function Support, Arduino is much more convenie
