PURPOSE: A building environment monitoring device is provided to monitor temperature, humidity, fire occurrence, trespassers, and power failure by connecting each building unit to a client PC. CONSTITUTION: A sensor module(S2) senses a building environment signal. An interface unit(S3) communicates with a client PC. A DC power supply(S4) supplies DC power to each module and an MCU(S1). A microcontroller unit includes the MCU. The microcontroller unit collects signals of the sensor module.
