HC-SR04 Ultrasonic Distance Sensor Board

Ultrasonic sensors use ultrasonic sound waves to measure the distance to the object. This sensor board has a receiver and transmitter. We know that how fast sound waves travel into the air. In this sensor board, we transmit sound waves and receive reflected waves. We can find the distance to the object by calculating the elapsed time.  This ultrasonic sensor board has a 0,1" sensitivity and 1-150" range. It can be used in distance measuring, radar, and robot applications. You can make a smart car with Arduino or other microcontroller boards, automated parking projects or all kinds of measure distance projects.  Operating Voltage DC 5V Current Draw 15 mA Operating Frequency 40 Hz Maximum Sight Range 157.48" Minimum Sight Range 0.787" Sight Angle 15° Trigger Pin Input Signal 10 us TTL Darbesi Echo Pin output Signal Input TTL signal and Distance Ratio Dimesions 1.78"x 0.80"x 0.60" Documents: Sensor Datasheet Example Arduino Application
