A data logger is an electronic instrument equipped with a sensor or accepts an sensor input. It has electronic circuity and on board memory that is programmed to record data at preset or user defined intervals for future analysis. The sensor measures real world environments or sourced from other equipment. The data collected by the sensor is converted into electronic signals by the chip, which then proceeds to store the information in its internal memory. A data interface mechanism (ie: Cable or Bluetooth) allows the logged data to be accessed for analysis and interpretation on pc's, tablets and phones.
