2、JMⅡ——Infrared Detection
The Micromouse infrared transceiver sensor circuit is shown in the figure. IR1~IR4 are infrared emission signals to drive the corresponding infrared emission. The infrared control signal sent by the processor is amplified by the MOS tube to control the on and off of the infrared emission tube to keep the emission frequency of the infrared emission tube at 1kHz. DETECT1~DETECT4 are received by the IR sensor. The received infrared reflected signals are respectively connected to the four A/D channels of the processor, and the processor calculates the current distance of Micromouse from the obstacle according to the received voltage value.
