The SD-2×1Wire Environment Monitor with WiFi is an environment monitor for connecting thermometers, humidity sensors and other devices via a 1-Wire bus. Up to four sensors can be connected, using a 1-Wire or a 1-Wire UNI bus. For configuration the SD-2×1Wire has a built-in web server and WiFi connectivity and the device can be remotely monitored over the internet using the SensDesk portal or SensDesk Mobile App (iOS or Android). Using SensDesk the device can send email alerts when the measurements are outside a specified range of values. Text messages (SMS) can also be sent via the SensDesk, if an SMS-GW3 module is attached to the network.
