Humidity Logger vs. Temperature Logger: Key Differences

This article breaks down the key differences between humidity loggers and temperature loggers. Essentially, a logger is a device equipped with a sensor that measures a specific parameter, processes the data, and then displays or stores the results as needed.

Simply put:

  • A humidity logger measures relative humidity.
  • A temperature logger measures temperature.

Both types usually feature a USB interface for easy data transfer to a computer or laptop. They also typically have ample memory to store numerous readings.
