Humidity data loggers are instruments used to record humidity for a predefined time. Humidity and temperature data loggers are primarily used in the shipping and logistics industry. The loggers are equipped with internal memory data storage, microprocessors, and sensors for reading humidity and temperature of the environment. Manufactures are providing data loggers with light and wind sensors for measuring wind speed and direction. These help in maintaining record of light intensity, which is important during transportation of products. In order to record the humidity and temperature inside containers, shipping and transporting companies use portable humidity data loggers and monitors. Data loggers provide reading of humidity level, which is useful for maintaining the quality of products. Manufactures are also offering portable humidity data loggers which work in critical environmental conditions. Humidity data loggers are also used in warehouses, indoor farms, and libraries.
