Simply put, a data logger is an electric device or gadget that records data over time. Some types record information in relation to the environment. A typical datalogger has an inbuilt sensor or instrument, battery, microprocessor and internal memory. There are however types that have external sensor or instrument.

With the advances in technology, these devices have become less expensive. A typical data recorder will cost you somewhere between twenty five dollars to several thousands of dollars depending on the complexities of the gadget. In the article, data recorder applications and factors to consider when selecting a datalogger are discussed.

The ability of this electric device to collect data over an extended period of time is one of its major advantages. These devices can be set and left for up to twenty four hours unattended to. It could be streaming in live info or it can store this information for future references. This capability is quite attractive especially if you do not have the personnel or manpower to keep monitoring the gadget continually.

This device can be used in several applications. It can be used in unattended weather stations where it can records information such as humidity, temperature and so on. Environmental monitoring, motor sport racing and road traffic counting are other applications the gadget can be used on. Before choosing a datalogger it is important to consider the following factors.

The input signal of the device.

You will find that some gadgets take in a number of signals while others only use a specific signal. You must consider this factor to avoid purchasing a datalogger that you can not use. Some common signals that are of use by most dataloggers include AC voltage, frequency, thermocouple and PH pressure.

The number of inputs the gadget can take.

You will find that some gadgets can take in several inputs at the same time. If your test will require several info or data originating from different inputs, your datalogger must be able to take care of this issue. Your test may for instance use frequency and AC voltages as input signals.

The size of the gadget.

Size is an important factor to consider especially if space is limited. These devices come in all different shapes and sizes that can suite the required specification. Of course if space is not limited, then this factor becomes redundant.

The speed and memory of the device.

The gadget must be able to store the required information. You can use the data logger sample rate to determine the memory of the gadget. A device that has a high sample rate would obviously require a lot of memory. For example, if your gadget\’s sample rate is one per second and your test runs for one hour, then you will need to have a memory that stores thirty six hundred samples in one hour. So, as you can see this is a very important factor to consider. If you\’re to pick a datalogger with a different memory and sample rate specifications, it would be difficult to acquire your target.
