WiFi Temperature / Humidity Data Logging Sensor

Now Cloud Enabled!*


The EL-WiFi-TH sensor measures the temperature and humidity of the environment in which it is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed using a free software package. 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 60 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.

This EL-WiFi-TH is a low powered battery device. When configured using typical sampling periods (e.g. once every 60 seconds) 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. 

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.

This sensor stands alone by itself on a horizontal surface and comes with a wall bracket that can be screwed onto a wall or flat surface. The sensor clips into the bracket.


Temperature and humidity data acquisition and monitoring has applications in a range of industries including: meteorology, building monitoring, server room monitoring, energy usage, pharmaceutical, HVAC, agriculture, horticulture and environmental studies. Sensors can be used across the food industry from manufacturing and storage to distribution and retail. Other sensitive products that require temperature monitored environments include medical vaccines, historical artifacts and wine. The unit is small enough to ship with packaging of perishables and can be checked in-situ using the WiFi network in transit and/or at drayage points.

* EasyLog Cloud, powered by FilesThruTheAir™

The EasyLog Cloud, powered by FilesThruTheAir™, takes our EL-WiFi sensors to a new level, unshackling them from the PC and allowing them to be managed and monitored over the internet from any location in the world. Users can interact with their sensors via a web based interface which allows them to monitor multiple EL-WiFi sensors in any number of locations. This gives the user the power to potentially monitor hundreds of sensors in different countries from one location. Not only does it provide the ability to manage and monitor the sensors, but users can also access event logs, which will give a record of any past triggered alarm events and have the ability to graph their sensor data online. Users also have the ability to set up email alerts which will notify them when an Alarm Event occurs.
