Welcome to the home of HawkEYE. Monitoring and reacting to the frequency of the mains supply has never been easier.
HawkEYE will monitor and react to frequency thresholds. 3 built-in relays can control external hardware within 20 milliseconds of a threshold being breached. The 1U rack mounted case also contains a display of the current frequency accurate up to 1000th of a cycle.
HawkEYE PLUS adds a Raspberry PI 3, 1.8" TFT and Ethernet connection to the HawkEYE. The frequency monitoring functions of the HawkEYE and added 1.8" TFT can be controlled over SPI from the Raspberry Pi.
