Use SPCE061A Singlechip, three Ultrasonic Ranging module to achieve ultrasonic reversing radar, requires the following features: 1. Can detect voice prompts modules within the scope of 0.35m ~ 1.5m within the scope of obstructions 2. Voice prompts may specify which direction (or regional) to detect obstructions in the framework 3. the use of three LED light-emitting diodes, said the scope of the three sensors to detect whether there are obstructions in the detection range when there are obstructions, the LED in order to a certain frequency of flashing, blinking frequency to set the distance from the nearer the higher frequency.
