The invention discloses an intelligent platform with a sampling circuit for house tenancy. The intelligent platform is characterized by comprising a central controller, a camera, a server, an intelligent lockset and multiple displacement sensors, wherein the displacement sensors are arranged on each home appliance of a house; information detected by the displacement sensors is transmitted to the central controller; the camera is arranged at a door; image information acquired by the camera is transmitted to the central controller; the central controller is used for controlling the intelligent lockset to be opened and closed according to a command from the server; a reservation management module is arranged in the server; the information detected by the displacement sensors is transmitted to the central controller after sequentially passing through the sampling circuit, a filtering circuit and an amplification circuit; the sampling circuit comprises an operational amplifier U1 and an operational amplifier U2, and a resistor R1 is connected in series with the in-phase input end of the operational amplifier U1. The advantage of reducing rent expenses is achieved.
