In the easiest terms, a data logger can be described basically as a device that stores data. Standard examples include serial communication systems or plug-in boards. The primary advantage of a data logger is that these devices can be controlled devoid of a computer. Data loggers can be categorized in accordance to storage capacity, shape/size, speed of recording and types of input signal.

The working of a data logger is equal to simple computing where user stores certain data on computer’s memory. Even so, data loggers use sensors which convert physical stimuli and phenomena into digital signals (e.g. current or voltage). The electric signals are further digitized or converted into binary data. Finally, that data is examined by software and saved on a storage media (CD or hard drive).

In the case of a data logger which is working off a GPS it will ‘log’ its place over a period of time, which you will later be capable to check on a computer. For instance, a haulage company could use them in its fleet and at the end of the day the loggers would display to the routes the drivers took and other data like speed and time.

Here is a list of components which are an important element of data loggers:

* Hardware: This helps digitize the signal that is being logged. This includes signal conditioning equipment, sensors and analog-to-digital conversion circuit.

* Onboard memory for data storage.

* Data-logging software: This helps in data acquisition, scrutiny, and presentation.

People would rather to use data loggers due to their ease of operation. Their structure and circuitry is simpler compared to a complicated computing system. Additionally, they are applied to guarantee you comply with market regulations, ensure product quality and save costs. When it comes to research work, data loggers are second to none. These instruments are normally far more economical as compared to chart recorders. Data loggers present greater input signal variety. Thinking of all these factors, they are the first alternative in data acquisition niche.

Data loggers are preferred by pros from various industries. They may be used for:

* Weather checking
* Food and agriculture industry for seeding, storage space and transport.
* Monitoring homes, warehouses, offices, or museums.
* Environmental monitoring of aquaculture, rivers, climate and oceans.
* In health care and laboratories.

If you are associated with stocking of data loggers, it is important that you mention all the features and qualities of your data loggers to your clients. Some of the features that can entice the consumer’s attention in the direction of your products include high-speed acquisition, long battery power life, big memory, and diverse input range, heavy duty business which can stand up to extreme weather conditions, easy-to-use software and rugged construction. All these features are bound to make an belief on your target market.

Purchasing data loggers, the other end of spectrum, is also as much important. Many things could go wrong here. Firstly, the data logger should be relevant to your industry. For instance, if you choose a fragile data logger for weather monitoring, it is sure to bring about problems throughout bad weather. Also, there is no use purchasing overpriced rugged-built data logger for lab use as chances of getting damaged are less. Another point to remember is to know your needs. If you do heavy data logging, give due importance to memory while shopping.

Here are some inquiries which you can ask on your quest to discover the great Data Logger:

1. Will it suit me?

Being aware of your requirements is the key here. The data logger’s feature set should be relevant to your industry needs.

2. Does it meet calibration standards?

The data logger must meet all the calibration standards of your industry. Also, the manufacturer must be certified and licensed.

3. Are the features enough?

Check all the features such as memory, speed of data acquisition, sample rate, number of inputs, and compatibility with other systems.

4. Do I need a computer?

No. Not during data acquisition. A PC may be required for data analysis, and storage purposes.

Over the years, data logging has emerged as a basic requirement in various industries.
