The infrared sensing circuit comprises a regulating circuit and an infrared sensor with model SN 926. The infrared sensor is used for detecting human body infrared signals and outputting control signals to the main control circuit, and the adjusting circuit is used for adjusting control signal output delay, ambient brightness sensing sensitivity and infrared sensing signal sensing sensitivity of the infrared sensor. The infrared sensor obtains an infrared signal through a phototriode Q1. The regulating circuit comprises three toggle switches, three groups of regulating resistors, a pull-up resistor R1 and a pull-up resistor R2. Taking the output delay adjustment as an example, the group of adjusting resistors includes three resistors, and the resistance values of the three resistors are different from each other.

Due to the voltage division effect of the resistors, when the pull-up resistor R1 is connected in series with different resistors, the delay control end of the infrared sensor can obtain different signal inputs, so that different delay outputs are carried out on the control signal. On the other hand, the adjusting resistor and the toggle switch can be replaced by a slide rheostat.
