Temperature Alert is an affordable (about $300) LAN-based temperature and humidity data logger for real time monitoring of temperature only (model TM-WIFI220) or temperature and humidity (model TM-WIFI220-TH). It includes a WiFi radio and hard wired Ethernet interface to easily connect to any network. The best feature is its built-in web server. Everything (setup, monitoring, data retrieval (.csv format)) is accessible via a standard web browser. There is no software to install. The standard probe measures temperatures from -55°C to +125°C (-67°F to +257°F). An extended range sensor is available that can measure temperatures from -200°C to +600°C (-328°F to +1112°F).
The Temperature Alert is available now and comes with an AC adapter and a standard 6-foot temperature or temperature and humidity probe.
