software program (known as embedded firmware) is stored on the data logger that controls the logger’s processes – some of which are defined by the user, such as the logging intervals from connected sensors. The data logger also has a data storage device similar to a puter, using FLASH memory to store files. This set of hardware and software work in tandem to collect and store data, control other instruments, and transmit data if the logger is connected to a telemetry radio device. A typical data acquisition application includes sensors connected or integrated with a data logging instrument at each physical location (See Figure 1). A telemetry modem (radio) is often connected to the data logger for wireless munication of the sensor data to a central office location. The central office location municates with the data logger from the remote locations using a data management software program. Inter access is typically provided from a separate customized program that integrates with the data management software program. 4 Figure 1. Flow of Data in a traditional example data acquisition system Today, a revolutionary change for data acquisition applications is available for those data collection sites that have Inter access (See Figure 2). The need for a localized data logging instrument and separate centralized data management software program is no longer required. Figure 2. Flow of data using the concept of cloud puting Instead, the user simply integrates the sensors directly to an IP (Inter Protocol) addressable telemetry modem for direct connectivity to the Inter program. The Inter software program placed on a remote server is programmed to municate directly with the remote modem and pull each sensor’s data. Data buffers can be included in the IP addressable modem for missed connections with the Inter Server. This works well with serial addressed digital sensors (such as RS485 or SDI12), but is more involved with analog sensors. This revolutionary trend will also increase the demand for new smart sensors and for smart mobile phone applications for remote configuration and programming of sensors. The software program residing on the Inter cloud functions as a virtual data logger and can be programmed to execute multiple userdefined routines and utilize other web services for enhanced data analysis, reporting, notifications and control not possible with a typical data logging instrument. 5 Figure 3. An overview of how data from remote monitoring stations can be accessed from any puter or mobile device with access to the inter, by taking advantage of a virtual logging platform hosted on the cloud.
