SRF04 ULTRASONIC TRANSCEIVER
To a distance of 10.7 meters maximum results. Has a low current consumption. Minimum sensitivity distance is 26cm. Is preferred because the smaller size modules.
SRF04 ‘front side of Figure 2 are given in. As shown in Figure 4 has the port. Among them, 2 percent supply (+5 V), the other two pulse outputs (pulse echo output) and trigger input (input trigger pulse) is.
SRF04 TIMING DIAGRAM
Srf04 The working principle is briefly as follows: SRF04 ‘reputation minimum 10us to start working a trigger pulse as shown in the diagram SRF04’ reputation is applied to the trigger input. After applying these pulses SRF04 sends out ultrasonic waves and generates.
340metre/sani is known that the speed of sound in air, bounced off the surface of these sound waves are sent back period is calculated. This period is known, the sound velocity on the basis of the calculated distance from the apparatus body.
If done the calculations, pulse output from the pulse duration in the availability USN 58 ‘E division (cm = usn/58) can be calculated in centimeters away. If 18ms from If no pulse is produced on a larger object is detected, the output value of 36msn SRF04 again to drop to 0 volts level.

- What is the maximum distance this system can measure?
The system can achieve results up to a distance of 10.7 meters. - How does the SRF04 start its operation?
The module requires a minimum 10us trigger pulse applied to the trigger input to start working. - What formula calculates the distance in centimeters?
The distance is calculated by dividing the pulse duration in microseconds by 58 (cm = usn/58). - What is the minimum sensitivity distance of the SRF04?
The minimum sensitivity distance is 26cm. - Does the system use an LCD display?
Yes, the system includes an LCD to display the measured data alongside the 8051 microcontroller. - What happens if no pulse is produced after 18ms?
If no pulse is produced within 18ms, it indicates a larger object was detected, and the output drops to 0 volts level. - What are the voltage requirements for the SRF04 supply?
The supply port requires +5 V. - Can I download the source code and schematic files?
Yes, circuit schematics and source code files are available for download in a ZIP format.
