Dataloggers use a microprocessor, an internal memory for data storage, and a sensor to collect data. They are generally small and battery powered devices. Data loggers can either interface with a computer and use software to view and analyze the collected data or be used as a stand-alone device with a local interface. There are also wireless data loggers available.

The advantage of data loggers is that they can operate independently of a computer, unlike many other types of data acquisition devices. Data loggers are available in various shapes and sizes. The range includes simple economical single channel fixed function loggers to more powerful programmable devices capable of handling hundreds of inputs.

Data loggers can accept different input types. There are also multi-input data loggers that can accept two or more types of input, such as temperature and humidity or temperature and pressure. Some data loggers can even accept all types of input.

The most common input types include:Pressure: Pressure data loggers measure the pressure of gases and liquids, including atmospheric and water pressure.Temperature: These loggers can be used to measure extremely high and low temperatures as well as liquid temperatures.Humidity: Humidity data loggers can collect data on relative humidity, dew point, and water vapor concentration in standard or metric units.Voltage: Voltage data loggers can adapt to any voltage measurement, including pressure to torque and load to force.Current: Current data loggers include a range of AC and DC data loggers and are often used to monitor building equipment.

The recording duration depends on the memory capacity of the data logger and the desired sample rate. To determine the duration, divide the memory capacity (number of samples the device can record) by the sample rate. As an example, assume that a given data logger can store 10,000 samples. If you want to record two samples every minute, the data logger can run for 10,000/2 or 5,000 minutes (about 3.5 days).

Depending on the type of data logger, you can either access the data directly within the data logger and even print it out, connect the data logger to a computer to extract the data, or data can be wirelessly transmitted in real-time to any connected device.

Data loggers are normally more economical than chart recorders. They offer more flexibility and are available with a greater variety of input types. Most data loggers collect data which may be directly transferred to a computer. Although this option is available with some recorders, it normally adds significant expense to the recorder price.

Data acquisition systems offer a great deal of flexibility and are certainly attractive when high sample rates are required. However, since they require connection or installation into a computer, the computer must also be present and active when collecting the data. Data loggers can collect data independently of a computer. Data is normally collected in non-volatile memory for later download to a computer. The computer does not need to be present during the data collection process. This makes them ideally suited for applications requiring portability.

A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL). They generally are small, battery-powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.

Data loggers vary from general-purpose types for a range of measurement applications to very specific devices for measuring in one environment or application type only. It is common for general purpose types to be programmable; however, many remain as static machines with only a limited number or no changeable parameters. Electronic data loggers have replaced chart recorders in many applications.

One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. This allows for a comprehensive, accurate picture of the environmental conditions being monitored, such as air temperature and relative humidity.

The cost of data loggers has been declining over the years as technology improves and costs are reduced. Simple single-channel data loggers cost as little as $25. More complicated loggers may cost hundreds or thousands of dollars.

Standardization of protocols and data formats has been a problem but is now growing in the industry and XML, JSON, and YAML are increasingly being adopted for data exchange. The development of the Semantic Web and the Internet of Things is likely to accelerate this present trend.

Several protocols have been standardized including a smart protocol, SDI-12, that allows some instrumentation to be connected to a variety of data loggers. The use of this standard has not gained much acceptance outside the environmental industry. SDI-12 also supports multi-drop instruments. Some data logging companies are also now supporting the MODBUS standard. This has been used traditionally in the industrial control area, and many industrial instruments support this communication standard. Another multi-drop protocol that is now starting to become more widely used is based upon CAN-Bus (ISO 11898). Some data loggers use a flexible scripting environment to adapt themselves to various non-standard protocols.

The terms data logging and data acquisition are often used interchangeably. However, in a historical context, they are quite different. A data logger is a data acquisition system, but a data acquisition system is not necessarily a data logger.

Data Loggers are changing more rapidly now than ever before. The original model of a stand-alone data logger is changed to one of a device that collects data but also has access to wireless communications for alarming of events, automatic reporting of data, and remote control. Data loggers are beginning to serve web pages for current readings, e-mail their alarms, and FTP their daily results into databases or direct to the users. Very recently, there is a trend to move away from proprietary products with commercial software to open-source software and hardware devices. The Raspberry Pi single-board computer is among others a popular platform hosting real-time Linux or preemptive-kernel Linux operating systems with many

Data loggers from DATAQ Instruments address a wide range of applications, both for general- and special-purpose situations.

The CR800 is a smaller, research-grade data logger designed for stand-alone operation in harsh, remote environments. It is intended for smaller configurations in which fewer sensors will be measured. Each CR800 reads input from sensors, then transmits the data via a communication peripheral; most sensors and telecommunication devices are compatible. Multiple CR800s can be configured as a network or units can be deployed individually.

The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.

With several channel types, the CR800 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR800's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

The CR800 communicates with a PC via direct connect, NL201 Ethernet Interface, multidrop modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat.

Data can be viewed on the CR1000KD Keyboard Display, CD100 Mountable Display with Keypad, user-supplied iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

Any 12 Vdc source can power the CR800 datalogger. Power supplies commonly used with the CR800 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 A h rating at 20C.

Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 A h, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).

Note: This OS has crossed the 2 Meg CR800 size limit for remote download. The OS must be downloaded to the 2 Meg CR800 via direct connect with the Device Configuration Utility. All OS download methods are supported by the 4 Meg CR800.
