This WiFi-enabled temperature data logging sensor can remotely monitor an environment over a -40 to 125 °C (-40 to 257 °­­F) measurement range. Data is uploaded periodically using a standard WiFi network to the EasyLog Cloud or a single host PC. Supplied with thermistor probe and mounting clip. EasyLog Cloud gives access to each data logger, and data collected from any internet-enabled device. Change data logger settings remotely, receive email alerts of alarm conditions, link sensors from multiple sites into one account and assign multiple user privileges.
