To help facility managers ensure temperature and humidity conditions stay within required parameters, Sensaphone® has added a new combination sensor to its line of remote monitoring equipment for HVAC and building automation applications. Because this new combination sensor communicates via Modbus, it is used exclusively with Sensaphone's Sentinel PRO system to monitor indoor air temperature and humidity levels. The Sentinel PRO sends an alarm notification when the temperature or humidity falls outside of the programmed high or low limit. The cloud-based Sentinel PRO system provides users with on-demand, real-time status of environmental conditions, as well as data logging capabilities.
