Light-controlled switch circuit based on molybdenum disulfide transistor

The invention discloses a light-controlled switch circuit based on a molybdenum disulfide transistor, which mainly solves a problem that the existing light-controlled switch circuit cannot work in ultralow light intensity. The light-controlled switch circuit based on the molybdenum disulfide transistor comprises a NPN triode Q1, a PNP triode Q2, an LED light emitting tube, the molybdenum disulfidetransistor VT, two voltage dividing resistors, a switch and a power supply. A grid of the VT is connected with an anode of the power supply through a first voltage dividing resistor R1, a drain of the VT is connected with a base of the Q1, a source of the VT is connected with a cathode of the power supply, an emitter of the Q1 is connected with the cathode of the power supply, a collector of theQ1 is connected with the base of the Q2 and is further connected with the anode of the power supply through a second voltage dividing resistor R2, the emitter of the Q2 is connected with the anode ofthe power supply, the colle
