HC-SR04 Distance Measurement using 8051 Timer Gate Mode
Simulating ultrasonic ranging in Proteus with an 80C52 microcontroller requires precise timing to capture the ECHO pulse duration. This implementation utilizes a crystal frequency of 11.0592 MHz and leverages the hardware GATE control feature of the 8051 timers to measure the high-level duration of the pulse without CPU-intensive polling.
