What is a data logger?

A data logger is an electronic device which automatically monitors and records environmental parameters over time, allowing conditions to be measured, documented, validated and analysed.

Data logging devices are generally stand-alone, battery-powered units. This makes data loggers advantageous in areas or environments where there is no electrical supply.

Data loggers receive external environmental information via one or more sensors and store the information internally on a memory chip. The information stored on the data logger is then transferred to a computer for analysis.

Data loggers can monitor parameters including temperature, humidity, single and three phase power usage, CO2, mV, mA, voltage and count (pulses).
