A temperature data logger is an electronic device that is used in computer controlled systems that monitors and regulates temperatures in domestic and industrial environments. The devices are usually incorporated in temperature sensors, implements which have extensive applications in the food industry as well as temperature controlled storage.

For many years temperature sensors were built with analog control and functionality. They required specialized equipment for monitoring and control. Modern sensors now have digital functionality and can integrate easily with digital computers easily.

In a data logging system, there are a number of essential components, each of which plays a significant role in the operation of this system. These include the temperature sensors that respond to any changes in the temperature in the immediate environment by generating an electronic signal.

The signal from the sensors is then sent to signal conditioning hardware. This is essential to moderate the unprocessed information for input. Since the temperature or heat sensors are always analog devices, the signal will similarly be in analog format and in this form cannot be processed by a digital computer.

The signal conditioning hardware will submit it from an analog to digital converter or ADC device. The ADC component of the temperature the logging system will convert the it to digital formats that can be processed readily by a computer.

The other hardware component is the computer itself. Modern temperature control devices are primed to work on standard computers. So long as the PC has plug and play hardware support, it will be more than adequate for the purpose.

To monitor temperatures adequately, some special purpose software will be required. The software will invariably come with the package that the device came in. There may be a requirement to download some updates so that the software integrates well with the operating system of the computer on which the system is installed.

When purchasing a temperature monitoring system, it is important to take care of several pertinent considerations. One important factor is whether the device interfaces with the computer by cable or wireless means. There are advantages associated with either form of interfacing. If the device can be programmed to either of these two this is an added plus.

For devices that use cable connection, it is important to consider if they come with a Universal Serial Bus or USB connector. If this is the case, then integration into the computer system will be much easier.

Another important consideration before acquiring such a device is to consider if the system is capable of collecting real-time information. This is especially important for industrial applications such as chemical control systems where even slight measurement errors can result to faulty products.

As with any electronic device purchases, a buyer should consider the terms governing the warranty given. Any precautions about the device operation should as well be considered including any personal safety issues or power specifications. Finally, a temperature data logger is usually powered by a battery and this should be replaced as regularly as the manufacturer requires.
