 "equipment_type": "Room dewpoint / humidity sensor",
 "applies_to": "Greystone DPRC series room dewpoint transmitters (PICS model DPRCB) with BACnet MS/TP.",
 "summary": "The DPRC is a Greystone room sensor that measures temperature and RH and calculates dewpoint, wet bulb and enthalpy, all reported as Analog Inputs over native BACnet MS/TP. Analog Values hold offsets, barometric pressure/altitude and the display mode; two Binary Values pick the units.",
