Description
Ultrasonic Distance Measuring Device
The ultrasonic distance measuring device is based on an STC89C52 microcontroller and incorporates an HC-SR04 ultrasonic sensor, a 3-digit LED display (Nixie-style), push buttons, and an active buzzer.
Features
- Button functions (from left to right): −, +, and SET.
- Microcontroller: STC89C52.
- Adjustable alarm distance. Press the SET button and use the + or − buttons to modify the alarm threshold. Settings are retained after power-off.
- When the measured distance is lower than the preset alarm distance, the buzzer is activated.
- Measuring range: 5 cm to 4 m.
- Suitable for use as an automotive parking sensor.
- Provides a wide measuring range, stable performance, and simple operation. Ready for use immediately after power-up.
Electrical Specifications
- Supply voltage: DC 4.5–5.5 V
- PCB dimensions: 60 × 70 mm
- Overall dimensions with sensor: approximately 60 × 90 × 30 mm
