Sentinel Pro II SHT11

Temperature & Humidity Wi-Fi Sensor

The Sentinel Pro II SHT11 incorporates the latest low-power Wi-Fi sensing technology. The Pro II version comes with up to 2 external temperature probes for remote monitoring of refrigerators, freezers, incubators and various other applications, as well as a built-in calibrated digital temperature & humidity sensor with long-term stability. This sensor is adapted to a wide range of applications including ambient air monitoring for server rooms, museums, libraries & hospitals.

The Sentinel Pro II series include a power switch, a pushbutton switch as well as a 3-color LED (for helping deployment). Please refer to the Solutions section to view all the possible usages for the Sentinel Pro II series.

Features & Benefits

Wireless temperature sensor
No need for cables, installation is straightforward; sensors can easily be moved around
Reuses existing Wi-Fi networks
There is no need to invest in a new wireless infrastructure. Your existing Wi-Fi network can be used for many more applications (web, voice, other sensors)
On-board flash memory
Will store data on the embedded flash if the network is temporarily unavailable
Extended battery life
The provided 3.6V AA lithium battery can last for up to 5 years (depending on settings and network quality).
Built-in digital temperature & humidity sensor (SHT11)
Designed for ambient air monitoring
