ROOM HUMIDITY, TEMPERATURE AND PM SENSOR AERASGARD® RFTM-PS MODBUS Multifunctional indoor climate sensor AERASGARD® RFTM-PS-Modbus with Modbus connection, in an elegant plastic housing with snap-on lid, base with 4-hole attachment, optionally with/ without display, The room sensor is used to detect the measurands air humidity (0...100 % r.H.),temperature (0...+50°C), air quality (0…100 % VOC), fine dust (PM) (0...1000 μg/m)and CO2 content (0...5000 ppm) as well as a room control unit (% setpoint). Use just one device to monitor and control the entire indoor climate effectively. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. It is used in offices, hotels, convention centres, apartments, shops, etc. A long-term stable, digital humidity and temperature sensor guarantees exact measurement results. The air quality is determined based on a (VOC) mixed gas sensor. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). An optical particulate sensor precisely detects fine dust (PM) of the size category 0.3 to 10 micrometers. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible. Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance, DIP switches for setting the bus parameters and bus address in the currentless state, LEDs for telegram status display and two-line display (illuminated; with customised programming in the 7-segment and dot-matrix range).
