EL-WIFI-TP

## **EL-WiFi-TP** External Thermistor WiFi Temperature Sensor 

- Thermistor probe temperature measurement range -40 to +125°C (-40 to +257°F) 

- Wirelessly stream and view data on the EasyLog Cloud, App  or on a PC 

- Easy sensor set-up using free PC software application 

- 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 

The EL-WiFi-TP measures the temperature of the environment in which the probe is situated. Data is streamed wirelessly over any compatible WiFi network and can be viewed on a PC using free software or on the EasyLog Cloud or App. 

To configure the sensor for use on a given wireless network, either connect it via USB to a PC running EasyLog WiFi software on the network, or configure wirelessly using the EasyLog Cloud app on a mobile phone with access to the network.  The sensor can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application or EasyLog Cloud (max 30 days at 10 second sample interval). 

The sensor is IEEE 802.11bgn* (2.4GHz) compliant, supports WEP, WPA/WPA2 encryption and enterprise networks (PEAP, TTLS, FAST). 

The EL-WiFi-TP has a protection rating of IP42 and the probe IP67. The unit is freestanding, but can be attached to a wall or surface using the bracket provided. The unit can be clipped in and out of the bracket as required.

## EL-WiFi-WIN 

Lascar’s WiFi software* is available as a free download from: www.lascarelectronics.com/software/easylog-wifi. Easy to install and use, EL-WiFi-WIN allows easy connection of sensors to a WiFi network. The user can select where data is stored - the PC or the Cloud. 

## Battery Life and Power Supply 

The battery can be recharged (unit must be between 0 - 40°C) via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided.  It can also be permanently powered by a USB wall adapter or USB battery pack. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect. 

Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature. 

Specifications liable to change without prior warning
