Intelligent socket having sampling circuit

Abstract

The invention discloses an intelligent socket with a sampling circuit, which comprises a power supply module, a housing, an electrode sheet, a pressure sensor, a single-chip microcomputer and a relay. The housing is provided with a socket hole, and two socket holes are arranged on the inner wall of the housing corresponding to the socket hole. An electrode piece, a pressure sensor is set in the middle of the two electrode pieces, the signal detected by the pressure sensor is transmitted to the single-chip microcomputer, the single-chip microcomputer controls the action of the relay according to the signal received from the pressure sensor, and the power supply module provides DC power for the single-chip microcomputer, and the pressure sensor and the single-chip microcomputer A sampling circuit, a filter circuit and an amplifying circuit are connected in sequence, the sampling circuit includes an operational amplifier U1 and an operational amplifier U2, and the resistor R1 is connected in series with the non-inverting input terminal of the operational amplifier U1. Realize the advantages of avoiding electric shock and enhancing the safety of the socket.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to an intelligent socket with a sampling circuit.
