Is the firmware for SRF04 - Devantech ultrasonic ranger available ? I have seen the schematic on the Devantech site, but unable to locate the firmware to make it work ! Can the firmware from the PIC on the SRF04 - Devantech ultrasonic ranger be read out ? Or is it code protected ? Has someone tried making a clone of (...)
hello can some one please tell me how i can measure beyond 255cm i2c mode with the SRF02 ultrasonic ranger? I can read the LOW byte but reading the high byte seems confusing....or can i only read upto 255cm? it does not say anywhere on the data sheet i have observed that when lowbyte goes beyond 255, then the highbyte goes to '1' othe
hey are there(this forum) any human????? No just aliens !!! Check this out (PIC):
i have an ultrasonic reciever written on it AND the transmitter . I couldnt know anything about it because i couldnt get the datasheet . am going to design an ultrasonic ranger using pic16f877a and some amplifires please help thx

Hey, I'm looking to get help with using my parallax ultrasonic sensor and my pic 16f887 to measure the distance to an object. I've checked around and found some useful information but none of the programs i've found were in C language. Anyone think they can point me in the right direction? thanks
I was looking for how to interface the ultrasonic rangefinder with AVR and from a website i found the following steps ultrasonic Range Finder Interface. These modules are designed to be used for microcontroller based applications hence optimized for it. The interface is a single pin called SIG (signal). The MCU is connected to the (...)
Here's what you need. Havent tried the circuit myself, though. If you do buid it, it would be nice to have your observations posted back on this thread. Regrada, Anand

Now I'm trying to make my robot and this is my first time... I have Servo and I'm trying to control the servo with Ping)))... so the robot can stop... But I met alot of trouble with Ping)))... Can anyone give an Advice or help me, How to use Ping))) with AT89S52... if necessary I need the "ASM file" cause I'm using Assembly language...
But is there no way of rather detecting the intensity of the reflected light and using that information to determine distance. You can use the reflected light intensity only if you always approach the object at the same angle. IMHO, an ultrasonic ranger is easier to build from scratch than a triangulating IR ranger
Hi... I am working on the "ultrasonic range finder".. in this I have to calculate the distance of the obstacle using ultrasonic sensor. In this case, I am stuck with the problem, If there are more than one obstacle in path at different distance, how to detect them with one sensor only & how to calculate the distance of each & every obstac
Hi, I was about to start a project "UltraSound Range Meter". In the receiver section, i was seen that there are 2 stages of amplifiers in order to amplify the received signal to 1000 times. Can i use a single stage amplifier instead of 2 stages???? Check this out, it's very simple :
Does any have C code for PIC 16F877a with the SRF05 module that has a pulse output proportional in duration to the range distance. I suspect this uses the capture mode. Here is a fairly good tutorial: SRF05 - Ultra-Sonic ranger FAQ: [URL
Hi members, Who knows itself with ultrasonic Transducer units for Hunidifier? I'm looking for some basics about this parts and driver circuits to make an Humidifier. The Transducers are working like an big crystal (i think so) at 1.6 - 1.7 MHz. I'm happy to hear from you and thanks in advance. Roscoe
why bother with electronics one a simple blow of a whisle the whisle is of the ultrasonic band made of metal will give the desired wavelengh and the tension you play can than be used too command the dog etc ..... other than this build a simple pic 16f84 pwm output you can then adjust via so
Hi, guys: I am looking for high frequency Medical ultrasonic Imaging system analog and RF circuit design, simulation and test stuff.

Would anyone share articles, tutorial
Hi, Where I can find a special integrated circuit suitable for ultrasonic piezoceramics. I want to us it in a water flowmeter. Thank you MSP430
The PSoC Range Finder is a simple, inexpensive ultrasonic distance meter that requires only the PSoC device, two 40-kHz ultrasonic transducers, two resistors, and two capacitors. Typical applications include positioning for robotics, generic distance measurement, and liquid-level measurement without contact.
I need a small ultrasonic cleaner . Cup size about the size of a cup of coffee . Rotring used to have such a device to clean plotter pen's . But it's been discontinued years ago . Has anyone ever done this or any info on this ? I thought i'd get me a small aluminium cup and attatch one or more ulrasonic transducers to it .Then d
Hi I have built an ultrasonic transmitter (using 40khz & 555). I'm trying to build an ultrasonic receiver circuit and have the output displayed on 7 segs or LED displays. What would steps would I need to take to build it. Thanks

Hi In the EPE mag issue from Aug/Sep 2003 this ultrasonic windspeed measurement is used. Depending upon accepted error and distance between tranducors I do not think you have to measure the temperature. It calculates the difference in speed of sound, running with the fluid/wind or in the other direction. Take a look at the schematic and code
I want a simple obstacle avoiding circuit using ultrasonic transducers for my robot
Hi, Here is a project that was writen for the MSP430, it has a schmatic and also source code in ASM. Mayby you can use that as a referance to write your code to the PIC. Good luck.
HI My project is Wireless digital video transmitter and receiver and I found the ranger 350i is suitable for this application but I found its price too much to buy so I want to ask about the circuits of this trnsmitter to make its design by myself or any sites which help me for design.
hi all the schematics below is from epemagazine this circuit work at 40khz ultrasonic transmitter and receiver but i only had 32 khz so how can i modify this circuit to work with 32 khz thanks for cooperation
Piezoelectric ultrasonic transducers usually perform well over a wide range of receive frequencies. You didn't say what type transducer you have, but 10kHz sounds like a very friendly frequency. I would expect the transducer to accurately convert the acoustic signal into a voltage signal. If the input is a sine wave, then the output will be a sinew
We are looking to use ultrasonic sensors for our 4th year design project, and was wondering if anyone could recommend some sensors for proximity detection, as large range as possible. Should we build our own Rx/Tx pair, or are there modules made for this purpose already?
hi everybody, in fact it's always a signal processing stuff, what I'm in need of is the technics employed for measuring the speed of the sound in a fluid, it means when I'm receiving on my PC the signal of a transducer how could I treat it. It's not clear!! ok. I'm working on a measure of sound frequency and attenuation of ultrasonic signals, an
When i want to transmit echo sound through ultrasonic transducer, did the ultrasonic device acts like a switch to turn ON and OFF to generate the pulse and convert to sound wave? Thanks a lot.
Hi there, I need ultrasonic cleaner with effective dimensions of bath of about 400x200x150mm. I searched the net for such a device, but prices are about 800-1000$ that is much more that i can afford. I need information on how to build one. I saw on eda that there are some discussions but nothing i can use. As I saw piezo elements are used as el
