I would like to create a multiplex version of this range finder with 3 different 40 khz transceivers covering 180 degrees using arduino or other mcu. Need someone that understands wave patterns, signal processing etc. You may have to teach me how to use an oscilloscope. Perfect for an engineering student of grad. I have a bunch of other projects as well. Can do this in the morning or evening.

Hello, thank you for your job posting. I read your description about--Ultrasonic single transducer TR range finder jsn-sr04t I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

Hi dear client I am an expert in signal processing and have advanced knowledge in electronics and microcontroller. In the past, I have made the quality checking tools using ultrasonic wave. There I have detect the faults in bottle using FFT. Also I have realized the ultrasonic distance measuring tool for robot motion. So as far as I am concerned you will get good results working with me. Thanks for your attention. Warm Regard Mykyta M.

HI There jsn-sr04t has two signal pins marked Trig and Echo Trig is set off to pulse out signals at regular intervals, and echo pin is set to pulse in the same signal in the end we will have time taken for the signal to be sensed since last trigger, and a speed of sound in air with those data we are able to find the distance sensed by our sensor how about we use ESP32 as our MCU, we can run more instances of jsn-sr04t on the ESP32 as IT supports multi tasking send me a message so we can chat more please

I am working with Arduino, ESP8266, ESP32 & Microchip PIC microcontrollers. I have used Ultrasonic SR04 sensor many times to measure distance from the sensor like fore head temperature measurement, Water Level measurement, Obstacle avoidance robot etc. Also manufacturing Automatic Weather station DAta loggers, Rain fall data logger etc. We can do the project successfully & upto our satisfaction.
