The Lascar EL-WiFi-T+ sensor measures the temperature of the environment in which it is situated. This high accuracy version is accurate to +/-0.1 C. The data streams wirelessly over any WiFi network and can be viewed on a PC using our free software package or on The Lascar EL-WiFi-Cloud. During configuration, the sensor will search for an existing wireless network whilst physically connected to the PC. It 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 cloud service (max 120 days at 10 second sample interval). Although the datalogging sensors have an impressive range this can be increased by using WiFi extenders. The ELWiFiT+ is a low powered battery device. When configured using typical transmission periods (e.g. once every 5 minutes) the sensor will operate for over one year (at room temperature). The battery can then be recharged via a PC or USB +5 V wall adapter using the USB lead provided or can be permanently powered by the USB wall adapter. The software installed on the PC will allow set-up, data logging and data review. Set-up features will 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. The sensor is a free-standing unit, however, it can be attached to a wall or vertical surface using the bracket and screws/sticky pad provided. The datalogger's sensors require your wireless network to be IEEE 802.11b compliant. If you have an enterprise network or multiple access points with the same SSID, please contact us to discuss your application before placing your order.
