The structure of the intelligent infrared remote controller is as shown in figure 1, this device is composed of the single-chip microcomputer, the infrared receiving part, the display circuit, the memory, the button and undervoltage indication circuit. This circuit can be driven by two batteries. The single-chip microcomputer uses the infrared remote control transmitter chip BA5048, the operating power voltage is 1.5-5V. The memory, LCD and the infrared emitter all have the ready-made 3V voltage products, the common infrared receiver IC (such as the CX20106, HS0038) has the rated operating voltage of 5V, it is hard to find the low voltage infrared receiver.
