Data Loggers
A data logger is an electronic device that stores data provided by sensors embedded in a device or tool with an external sensor over time or in relation to location. Most data loggers are designed and built based on a digital processor. They are generally small and portable, powered by a battery, equipped with a microprocessor, and have internal memory for data storage and a number of sensors.
Some data loggers are connected to a computer and can be activated using software and monitored data can be viewed and analyzed, while others have a local interface (such as a keyboard and screen) and can be used as an independent device.
Dataloggers come in a variety of types, from versatile types used for a range of common uses to highly specialized devices for measuring only a predetermined environment or application. It is common for all types of machines to be programmable, however, many of them remain static machines with no parameters or a limited number of changeable parameters.
Electronic data loggers have replaced with chart recorders in many applications. One of the main advantages of using data loggers is the capability to collect information 24 hours a day. Data loggers are usually left unattended upon activation to measure and store data during the monitoring period. This feature allows to obtain a comprehensive and accurate picture of the conditions of the monitored environment such as air temperature or humidity.
Data formats
Standardization of protocols and data formats has been difficult in the past but is growing in the industry today. Among data storage formats, the Popularity of XML for information exchange is increasing every day.
Applications
- Storage at an unattended meteorological station (such as wind speed/wind direction, temperature, relative humidity, solar radiation).
- Storage at unattended hydrographic stations (such as water level, water depth, water flow, water pH, water conductivity)
- Automatic storage of soil moisture
- Automatic storage of gas pressure
- Counting road traffic
- Temperature measurement (humidity, etc.) of perishable materials during cargo transfer: Cold chain
- Process monitoring for maintenance and troubleshooting applications
- Wildlife research
- Measurement of vibration and transport conditions (drop height) in distribution.
- Tank Storage Floor monitoring
