The WiFi-21cfr-TH+ is a high-accuracy temperature and humidity data logger which uses a standard WiFi network to transmit data to the FilesThruTheAir™ 21CFR Cloud. 

During configuration, the sensor will search for an existing wireless network while connected to the PC via its USB cable. Once connected to the WiFi network, 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 21CFR Cloud (this will be maximum 30 days at 10-second sample interval). 

The unit is freestanding but can also be attached to a surface or wall using the supplied bracket. The device is IEEE 802.11bgn (2.4GHz) compliant, supports WEP, WPA/WPA2 encryption
and enterprise networks (PEAP, TTLS, FAST).
