Design and test a ph probe reading circuit

Hi, Here is my bid for the project. I am ready to proceed with the circuit design. Thank you. Junaid

Hi, I hope you are doing well. I have extensive experience in embedded system programming and development. I have ESP32 available for quick prototyping and testing. I have understood your requirements to interface ph probe and I can execute this project in less possible time. Looking Forward, Khawaja

Hi, I can design the interface front end for you, do you have a specific model of ph probe you want to use? The calibration function should be digital or can be analog (using trimpots for example)? let me know if you have any question. Best regards, Adriano

Hello I have got your job posting “Design and test a ph probe reading circuit” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the Analog/Digital Electronics Embedded systems(ESP32,Arduino,Rasberry pi ,ARM processors ,PIC microcontrollers,Wireless boards,TFT Touch Displays,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find that, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio. I have all the components available here with me so i will develop a working prototype according to your specifications and then send you the code and schematics so things will work for sure.I will remotely guide you and help you build the system on your side. I am always available on Email and Skype. Please have a voice or video chat if necessary. I shall be available round the clock and able to start your project as soon as possible according to you. Thank you for your consideration, Best Regards, Haseeb Shafqat

Hello my name is Maria, I would like to work in this project, I’m an engineer with plenty of experience working with Circuit Design, Electrical Engineering, Electronics, Microcontroller, PCB Layout , I have made many PCB projects, so I am sure I can do a good work for you. Good communication with my clients it is a top priority for me. If you have any doubt or want to see more of my work I’ll be here. Contact me for more info.

Hi! I'm Alberto from mexico, nice to meet you, can we talk a little more about your needs? and a little more about the sensor? I'm an electronics engineer, I have been working with the esp family since a year ago. I can do the job for you, but I'll need a little more of information. Regards

Hi i'm engineer, control expert, i have experience working in automation and control design & building, i can develop for you complete designs for building; plans, calculus' memories, controller's code and simulations; simulink, simscape, proteus

Hello, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . i already have the ESP32 PH with mqtt post made for another project , please tell me more about your requirements . I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteus (+simulation). i have an workshop full of parts and the infrastructure to build PCB and test the solution end to end using special tools (Spectrum analyzers , oscilloscope , logic analyzers ) Derivable on the project : Wiring diagram for prof of concept . Schematic design PCB Design Gerber files for manufacturing MCU code explained every line . As an additional service i can make you a full working prototype and ship to you. Regards, Andrei

Okay! This is possible! Here is the process to Design and test a ph probe reading circuit:- 1. Research & analysis 2. Schematic design 3. Component order 4. PCB layout design 5. Testing 6. Firmware development using ESP32 We are a professional team in Embedded system having hands on experience with circuit design & Firmware development. We will be glad to hear from you! Regards, Intellisense Technology

i can design this circuit using a op-amp gain circuit but will be required time to get accurate calculation for the measurement the PH value(i think it's good to add a temperature sensor with this for accurate measurement) .. And i am not a good programmer so programming will be Arduino IDE(for ESP32)... designing will be using KiCad i will give garber file with BOM.

yes buddy, its me imad, have done 200+ projects myself, i will make and ship u the complete prototype, u will get the best work done accompanied with brotherhood,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Hi. This project has already been made using ARDUINO. I realize the project, a prototype and I can send you the prototype, you pay the shipping. I include the list of materials, diagrams, programs and I teach you so you can transfer the program to ARDUINO:

Hi We are team of experts having 6plus years of exp in embedded systems, Iot, pcb design and dovelopment and prototyping. We are already build the pH probe hardware and firmware for bnc type probe. I think we are the best for this job. Thanks

Hi I’m Matt from Warton Circuits Ltd in the UK. We’ve got extensive hardware design and firmware experience, from coffee machines to HVAC heat pumps. We are currently working on an ESP design for another client, and would love to work on your project. Do you already have the pH probe? Could you provide a data sheet? We have full rapid prototyping facilities on site which means that same-day PCB manufacture can happen. Thank you for your time.

Electronics engineer* here. Sounds like a simple enough project. I'll need details on the probe and what kind of data the ESP32 expects, or your requirements basically. Just send a message if you're interested :)
