The Hawk is sold as a 'baseboard' and plug in cards are used to interface to sensors. 8 lines are available. This allows for a variety of sensor-monitoring applications and input combinations to be catered for on the same device. Additionally if you have a specific set of inputs to monitor, we can manufacture a new IO card to cater for your requirements (MOQs apply).
- BaseBoard
- This is the HAWK-4G device - Baseboard, housing, Internal LiPo back-up battery
- The baseboard handles the cellular connectivity, external power connections and has a single Digital Input available. There are 9 x I/O pins, which are used by the I/O cards. Their function is determined by what card is inserted.
- I/O Cards
- Allows the device to be connected to various interfaces. Current cards are listed below
