Smis Instrumentation We are Data Logger Suppliers Suppliers.
A data logger (also data logger or data recorder) is an electronic device that records data over time or in relation to 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). 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 utilize 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.
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 or other parameters being monitored, such as
3. Temperature and Humidity
4. Dew point
7. Sound level
8. Air velocity
11. Wind speed and direction
12. Rain Gauge
13. Weather monitoring data Logger and etc...
How does a data logger work?
First, the data logger is connected to a computer via a USB interface. Next, accompanying data logger software is used to select logging parameters (sampling intervals, start time, etc.) and activate the logger. The logger is then disconnected and deployed in the desired location, where it records each measurement and stores it in memory along with the time and date. Bluetooth Smart loggers can be configured and launched wirelessly, after deployment.
After the desired monitoring period, the data logger is then reconnected to the computer and the software is used again to read out the data and display the measurements in graphs that show profiles over time. Tabular data can be viewed as well, or exported to a spreadsheet for further manipulation.
In the case of web-based data logging systems, data are pushed to the Internet for access; with wireless data nodes, data are transmitted to a central receiver; and with Bluetooth Smart loggers, data are downloaded directly to your mobile device.
Where are data loggers used?
Data loggers are used in a broad range of indoor, outdoor, underwater and temperature-controlled environments - essentially anywhere data is needed and the convenience of battery power is preferred.
What are the different types of data loggers?
The four main types of data loggers are: stand-alone data loggers, web-based data logging systems, wireless data nodes, and Bluetooth Low Energy (BLE) data loggers.
Stand-alone USB data loggers are compact, reusable, and portable, and offer low cost and easy setup and deployment. Internal-sensor models are used for monitoring at the logger location, while external-sensor models (with flexible input channels for a range of external sensors) can be used for monitoring at some distance from the logger. Most stand-alone loggers communicate with a computer via a USB interface. For greater convenience, a data shuttle device can be used to offload data from the logger for transport back to a computer.
Web-based data logging systems enable remote, around-the-clock Internet-based access to data via GSM cellular, WI-FI, or Ethernet communications. These systems can be configured with a variety of external plug-in sensors and transmit collected data to a secure web server for accessing the data.
Wireless data nodes transmit real-time data from dozens of points to a central computer, eliminating the need to manually retrieve and offload data from individual data loggers.
