WiFi Temperature Data Logging Sensor
The WiFi-T measures the temperature of the environment in which it is situated.  Data is streamed wirelessly over any WiFi network and can be viewed on a PC or the FilesThruTheAir™ Cloud using the free software package.
It can then be placed anywhere within range of the network.
If the sensor, for any reason, temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application or FilesThruTheAir™ Cloud.
The LCD display includes several features including Max and Min readings, and an indicator for low battery, WiFi connection and signal strength.
The software installed on the PC will allow set-up, data logging and data review. Set-up features include sensor name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or exported into Excel. This software is available to download for free from the Support page.  Free firmware downloads are also available.
The sensor is a freestanding unit, however, it can be attached to a wall or vertical surface using the bracket provided.

  • Temperature measurement range -20 to +60°C (-4 to +140°F)
  • Easy sensor set-up using free PC software application (available on the Support page)
  • Wirelessly stream and view data via WiFi on PC or FilesThruTheAir™ Cloud
  • View and analyse multiple sensors, including graphing of historic data
  • Configurable high and low alarms with indicator
  • Sensor memory stores all data even if WiFi is temporarily disconnected

SquirrelView Plus Analysis
SquirrelView Plus lets you quickly and easily analyse the data from your Squirrel data logger in a familiar Explorer style interface. Data can be displayed with 2 different auto scaling Y-axes. This is particularly useful when displaying widely varying data from different sensors on one graph. You can also zoom in on areas of interest, use a cursor to pick out exact values, times and dates, get a
statistical summary of your data, set high and low alarm thresholds and, using the calculation function, you can create new virtual channels from existing channels.
SquirrelView Plus also incorporates a report generation facility, which allows you to create custom report templates consisting of a  yitle page with descriptive text, headers and footers, graphs, tabular list of data, statistics and data logger setup information. Templates can be setup with any of these combinations and saves time when preparing similar presentations of data.
