Humidity and temperature measurement

humiditySensor is a humidity and air temperature sensor that communicates via a local WiFi network. Thanks to the wBox application, remote communication from anywhere in the world is also possible.

The probe can measure humidity in the range of 0 to 100% and temperature in the range of -40 to +125 degrees Celsius. It is resistant to splashing water.

Multi-parameter indicator!

humiditySensor, in addition to humidity and temperature, can indicate:

  • thermal comfort – whether the temperature and humidity in the room are appropriate so that there are no electrostatic discharges, dry skin or mold on the walls.
  • heat index with warnings – a heat index warning against the possibility of getting a stroke due to high temperature and humidity
  • dew point – the temperature to which air temperature must be lowered for water to condense to form dew
  • absolute humidity – the amount of water in the air, given in grams

Versatile use

You can use the WiFi humiditySensor as:

  • Humidity and outdoor temperature sensor
  • Indoor humidity and temperature sensor
  • Humidity and temperature sensor in a sauna
  • Index of thermal comfort inside the rooms of the house
  • Heat indicator as a warning against staying outside (on hot and humid days)
  • Humidity and temperature meter for tropical plants in paludarium, vivarium, terrarium
  • Humidity and temperature meter in greenhouses (e.g. when growing tomatoes)

Automation, actions

humiditySensor, after exceeding the set temperature or humidity threshold, can wirelessly control as many as 30 other BleBox devices.

  • In combination with the switchBox LIGHT controller, control the fan in the bathroom or kitchen to get rid of excess steam and humidity
  • Combine with the switchBoxDC controller to create an automatic sprinkler to increase the humidity in your vivarium, paludarium or terrarium
  • In the greenhouse, it will open a window in conjunction with the shutterBox controller or start ventilation, heating in conjunction with the switchBox controller.

Charts and historical data

The interactive graph allows you to accurately check the historical temperature and air humidity.

For advanced users, there is an option to export data to a file to process it in another program.

Notifications, warnings

The sensor can also send notifications to the smartphone when the set temperature or humidity threshold is exceeded.

Plug & Play

Connect to a 5V charger (e.g. from a phone) and start working! WiFi humiditySensor doesn’t need anything else!
