The d.hat module from the D.HAT PDK, offering six channels of analog input and FW for single and three phase energy monitoring is available as a stand alone module for remote sensing applications where physical separation from the server is required.
Enabled by d.hat’s WiFi and USB connectivity when not directly coupled to the PI I/O connector GPIO lines, the remote connectivity allows for multiple d.hat boards to be linked to a single server engine. The figure shows an example in which one d.hat is directly connected to the PI server / gateway unit and is measuring input and output energy KPIs for a motor drive while a second d.hat is remotely mounted near the load and is monitoring motor and pump performance KPIs using its flexible input capabilities.
The DTECTS server engine has been updated to allow selection of d.hat interfaces on the setup web page. Once configured, d.hat data is sent to the DTECTS server for processing and visualization.
We have designed and printed enclosures for the board which allow both DIN rail and surface mounting. Each board is shipped with a 3d printed enclosure, DIN clip and hardware to allow mounting on most surfaces.
