WiFi Temperature &  RH  datalogger

Ambient Temperature and Humidity Sensing

This WiFi-enabled temperature, humidity and dew point data  logger can remotely monitor an environment over a -20 to +60°C (-4 to  +140°­­F) and 0 to 100% RH measurement range. Data is uploaded  periodically using a standard WiFi network to the EasyLog Cloud or a single host PC.

EasyLog Cloud harnesses  the power of IoT to automate data logging and alert notifications -  perfect for both compact systems with just a few sensor requirements to  corporate solutions with thousands of devices around the globe. Access  data collected from any compatible data logger. Change settings  remotely, receive email alerts of alarm conditions, link sensors from  multiple sites into a single account and assign multiple users with  varying access privileges. Use the EasyLog Cloud Apps for Android™ and Apple for true on-the-go monitoring.
Data Loggers in this range measure ambient temperature and humidity levels with the sensor built into the device. Monitoring humidity plays an important role when ensuring the efficiency of equipment and as part of responsible facilities management, monitoring temperature and humidity can help to keep customers and employees safe and comfortable.

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.
