Ultrasonic Serial Board

Ultrasonic Ascii serial O/P Board is an amazing product that provides very short to long-range detection and ranging. Its compact size, higher range, and easy usability make it a handy sensor for distance measurement and mapping. The board can easily be interfaced to microcontrollers RX pin (USART). At every 50ms sensor transmits an ultrasonic burst and sends out an Ascii value of distance that corresponds to the time required for the burst echo to return to the sensor.

Naturally, robotics applications are very popular, but you’ll also find this product to be useful in security systems or as an infrared replacement if so desired. Since it is very stable, the “ECHO” Ultrasonic sensor module can be used for Micro mouse application instead of the IR sensor.

Ultrasonic Serial Board Overview

The Ultrasonic Serial Board is a compact distance-measurement module based on an ATMEGA8 microcontroller, designed to output real-time ASCII distance values over a USART interface. Operating at 5V DC with less than 20 mA consumption, it emits an ultrasonic burst every 50 ms and returns distance data for mapping, obstacle detection, and automation projects.

Key Features of Ultrasonic Serial Board

• Onboard ATMEGA8 microcontroller handles signal processing and ASCII serial output
• Automatic ultrasonic burst every 50 ms, providing a 20 Hz update rate
• Low current consumption <20 mA at 5 V DC operation
• Compact PCB form factor for easy integration into tight spaces
• Simple UART interface: TX pin connects directly to microcontroller RX
• Fast shipping from Zbotic ensures you receive genuine modules quickly

Applications and Use Cases

• Obstacle avoidance in small robots and autonomous vehicles
• Proximity sensing for security and intrusion detection systems
• Liquid-level measurement in tanks and containers
• Mapping and navigation in indoor drone or micro-mouse projects
• Replacement for IR sensors in environments with strong ambient light

How to Use Ultrasonic Serial Board

Power the board with a regulated 5 V DC supply and connect its GND to your controller’s ground. Link the board’s TX (ASCII output) to the microcontroller’s RX pin, then configure your UART to the correct baud rate (e.g., 9600 bps). On power-up, the module will emit ultrasonic pulses every 50 ms and send back ASCII-encoded distance readings, which you can parse in your firmware for real-time measurement and control.

Frequently Asked Questions

How do I interface the Ultrasonic Serial Board with an Arduino?

Connect the module’s VCC to Arduino 5 V, GND to GND, and the board’s TX output to Arduino RX. In your sketch, initialize Serial at the matching baud rate (e.g., 9600) and read incoming ASCII strings to obtain distance values.

What detection range can I expect from this board?

The board reliably measures distances from a few centimeters up to several meters, depending on target reflectivity and environmental conditions, making it versatile for both close-range and longer-range sensing tasks.

At what rate are distance readings updated?

The Ultrasonic Serial Board emits an ultrasonic pulse and returns the corresponding distance as an ASCII value every 50 ms, giving you a continuous 20 Hz update rate for responsive measurement.
