RemoteWatcher (PPS33LR) is a low-power wireless multi-sensor monitoring system designed for applications that require simultaneous multi-point pressure, temperature and/or flow monitoring.
The system is highly adaptive and cost effective. Customers can start with the basic system that includes wireless logger and six wireless sensors. Then as requirements expand the system expands — by replacing the logger with a wireless router and computer — adding up to 60 individual wireless sensors.
