The Sentinel PRO from Sensaphone is a cloud-based, cellular system that provides remote monitoring of unattended equipment and environmental conditions in water and wastewater applications where internet or Ethernet connectivity is unavailable. The system supports the Modbus communications protocol and includes a second relay output to monitor and control complex networks. Only one unit is required to monitor up to 64 Modbus registers or 12 different digital or analog status conditions. Users can manage multiple devices from one account using web-based tools. The cellular system can be used for unattended pump stations, wells and tank farms because it can detect changes in conditions such as tank levels, flow rates, pump status, turbidity, power supply, temperature, equipment malfunction and security breach. When the system identifies an issue, it immediately sends alerts by phone, text or email over standard cellular networks provided by AT&T or Verizon. 877/373-2700; www.sensaphone.com.
