Description :
The DAWS2000 series of Weather Measurement Systems provide precision measurements using distributed intelligence, and are rugged and battery operated. The power consumption of the DAWS2000 series systems are made minimal for unattended operations. Every intelligent subsystem is switched to measurement mode when required so that the average power required is made small.
