Temperature & humidity measurement and wireless transmission

Temperature and humidity logger

Newsteo Data Logger for wireless measure of temperature, humidity and dew point

The Newsteo temperature and humidity logger is a wireless device which enables to oversee at distance the temperature and the humidity of an environment. Then, this temperature and humidity datalogger can transfer the data directly on a receiving station (monitoring computer, gateway) by radio frequencies or can store the data in its memory.

The product is available into 3 versions depending on the needed precision:

  • LOG20 : Temperature sensor accuracy : +/- 0.5°C and Humidity sensor : +/- 4.5% , dew point temperature
  • LOG22 : Temperature sensor accuracy : +/- 0.4°C and Humidity sensor : +/- 3% , dew point temperature
  • LOG25 : Temperature sensor accuracy : +/- 0.3°C and Humidity sensor : +/- 2% , dew point temperature
  • LOG12 : Temperature sensor accuracy : +/- 0.4°C and Humidity sensor : +/- 3% , dew point temperature,

Where the measurements will be displayed ?

2 choices to create your wireless sensor network:

  • Local single-site solution: you have a small installation (some dataloggers, located near the supervisory position). In this case, the RF Monitor software is appropriate. You install this software on a computer and connect the RF-to-USB Key (radio receiver, provided by Newsteo) to a USB port.

    •  

  • Multi-site solution with remote monitoring: you want to display the measurements of your dataloggers via different PCs located in different sites. The Newsteo Cloud offer allows you to send all the measurements of your recorders to the cloud and access it through a Web application, Webmonitor.

Who uses the temperature and humidity dataloggers?

  • Museum curators: an easy and convenient way to constantly check the humidity level
  • Fragile good storage: constantly monitor the level of temperature and humidity
