Temperature and humidity data loggers typically come with sensors built in that are able to measure humidity and ambient temperature in different settings. There are several popular applications for USB temperature loggers including:

  • Fridges and Freezers – For commercial food and pharmaceutical storage it’s critical that your fridges and freezers stay within the right temperature range. Temperature data loggers are ideal for this, especially the wireless models with alarms to SMS or email.
  • Greenhouses – Maintaining the correct level of humidity and temperature in your greenhouse helps to ensure that your plants thrive. A round the clock monitoring process with alarms, a wireless temperature logger is an excellent fit.
  • Warehouses – USB temperature loggers are popular in warehouses because humidity can encourage mould growth and spoil items. You can set up temperature and humidity data loggers around your warehouse and get multiple readings at once.
  • Attics and Basements – Keeping moisture out of your attic or basement is critical to keeping mould and mildew growth down. A temperature data logger will continually monitor these known problem areas and allow you to keep track of levels, so you can make any adjustments that are necessary.

Esis stocks humidity data loggers that use externally connected humidity and temperature probes to extend temperature readings to areas where you can’t place the logger itself, such as in an oven or in the centre of a bottle. Multi-channel loggers can also combine several temperature and humidity readings onto a single graph so you can see how things vary over time.

Where should I put my humidity sensor?

The main purpose of humidity sensors is to measure the humidity affecting particular objects, or affecting people. Hence you should place the humidity sensor at a location within the same area (sharing the air mass) of the objects or people involved. In addition, to avoid spurious readings, certain constraints also apply. Your humidity logger should be placed in an area that is away from radiant heat or cold to ensure that the readings are correct for your environment. A temperature and humidity meter should not be placed in direct light from windows or spotlights and should be away from direct air flow such as that produced by an air-conditioner.

Which sensor measures moisture level with temperature?

Whether you choose a wireless or a USB temperature and humidity data logger the sensors in each of our models are able to measure the water vapor and moisture in the air, as well as temperature, to provide you with an accurate humidity reading. The relative humidity is measured on a scale of 0 to 100%. Wireless humidity loggers can be fitted with an alarm and notification system to ensure that your readings are transmitted to you, no matter where you are.

How accurate are humidity sensors?

Typically humidity loggers come with accuracies around 3-5%, which is good enough for most applications. However in some cases the humidity needs to be regulated within very tight limits, for example in museums, pharmaceutical manufacturing, etc. For this kind of application, high accuracy humidity sensors are also available, with the best sensors accurate to 1% or better.

Does my phone have a humidity sensor?

Most newer phones do not have built in humidity sensors, but they do usually include a temperature data logger for the battery. If you have one of the few smartphones with a humidity sensor built in, there are apps that can be downloaded to measure humidity levels. Bear in mind a phone sensor will not be as accurate as using a project specific humidity sensor.

How long do humidity sensors last?

A data logger for temperature and humidity will typically last from 7 to 10 years, provided that it is kept in a clean environment and regularly calibrated. Contact us to discuss our calibration services for your humidity and temperature data logger to ensure that you are making the most of your equipment and that it, in turn, is providing you with the most accurate data available.
