Office building HVAC energy consumption accounts for over 40%. Traditional time-schedule control is highly wasteful. Human presence sensor XKC-LD002 is deployed by zone, combined with space zoning logic: maintaining 24℃ in occupied areas, switching to ventilation in unoccupied areas.
The cooling tower make-up water pool uses the capacitive non-contact liquid level sensor XKC-Y29A adhering to the FRP outer wall, converting continuous level to 4–20mA onto the BA system: open valve at low level, close valve at high level, avoiding the jamming and overflow issues of traditional float balls.
Both devices from Xingkechuang support industrial-grade power supply and Modbus, directly integrating into building management IoT, with a typical payback period of <8 months.
