WiFi Temperature Data Logger


The EL-WiFi-T sensor measures the temperature of the environment in which it is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed via the graphing tool or can be exported to Excel.

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. This software is available to download for free from www.lascarelectronics.com

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 (max 120 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.

The EL-WiFi-T 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. The battery can then be recharged via a PC or USB +5V wall adapter using the USB lead provided.
