The EL-IOT-1 is a wireless, Cloud-connected temperature data logger. It comes with an internal sensor with a -20°C to 60°C measurement range.  Handy status indicators on the front of the device alert you, at a glance, to alarms, battery levels, and WiFi connection strength.

The device is simple to set up and once configured the device can be placed anywhere within range of your WiFi network, continually monitoring and recording your data to the EasyLog Cloud. You can then use the Cloud to access, analyse, and share your data from any internet-connected device.

Set high and low-temperature alarms where an alarm is activated if your temperature threshold is breached. Alarm options include email alerts (which can be sent to one or multiple email addresses), sounder alerts and light flash alerts.
