Internet-of-Things monitoring system for building construction

The invention discloses an Internet-of-Things monitoring system for building construction. The system comprises a signal sampling module and an oscillation denoising module, and the signal sampling module is connected with the oscillation denoising module; the oscillation denoising module uses an operational amplifier AR2, a triode Q3, an operational amplifier AR4 and an inductor L2 to form a high-frequency interference filtering circuit to filter high-frequency noise in signals. The signal-to-noise ratio is reduced by using a capacitor C6; in order to further ensure that noise interference inthe signal is filtered out, a noise detection circuit composed of an operational amplifier AR3 and a capacitor C7 is used for detecting an emitter signal of a triode Q1, meanwhile, feedback signals of the triode Q3 is input into the inverting input end of the operational amplifier AR5 after being subjected to voltage division by a resistor R12 for further trimming, the signals are sent to the Internet-of-Things monitorin
