If you didn't bother to read this description before you replied, then I do not want you on the project. I am interested in monitoring the temperature of an oil bath cooling system based on hours and temperature. I am looking to use a PT100 thermocouple (perhaps analog with a 0-5v output) to a microcontroller. (perhaps a PIC 16F887 or something else reccommended) through a temperature sensor such as an LM35. I have 110vac power supply that will have transformed power at any voltage required. In addition to the temperature, there will be a pressure transmitter ( perhaps like a Honeywell PX2 series) that will signal when the equipment is on. The microcontroller will have a touchscreen interface (perhaps like a 2" TFT Display module as in the attached datasheet). A storage device to maintain daily record of date & temperature needs to be maintained for a period of 1year. A functional description is being worked on. However the basics will be that THM-01 will monitor the temperature of the oil. THM-02 will measure the ambient air conditions. PT-01 will monitor pressure to activate a timer that counts down hours off a given number internally. As conditions in THM-01 change, the output to the screen will change in accordance with a set of predetermined formulas in the program. The storage device will maintain the recorded temps. A sampling rate of 12 times per hour will be used in the process. It will be possible that 72k recorded data points be stored in the system before it is cleared. Various outputs to the screen will be made based on the condition on THM-01. Example would be that the graphics on the screen turn from blue to red as the temperature rises. In an upset condition determined by the firmware a simple signal will be sent to a PLC, I am thinking a switch with a binary condition. C++ will be used in this project. There is more to discuss, but Most will be covered in the functional description.

Hi Sir, We have previous experiance with temperature monitoring systems of blood incubators. data storage can be achieved using low power flash chips contains around 32-64 Mb in single chip.. We will send videos of previous projects later after discussion with you. Looking forward to hearing from you. Best Regards, Lasantha Prasad

Hello , How are you ? Hope all is fine ! regarding your project , I have worked on many control projects that included sensors (like Temp , Gas , IR , ...ect) .I also used many User Interfaces like LCDs (Graphical and Alphanumeric and touch). I use various platforms according to your demand , and I can show you samples of my previous work on my youtube channel. ----------------------------------------------------------------------------------------------------------------------------------------------------------- I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. I also have long experience with PCB design. I have worked with low-speed , high-speed and power boards. I use Altium Designer and Eagle, and I deliver neat layout that conforms to your dimension constraints and the manufacturing constraints. More to be discussed once you contact me . BR, M.T.

Dear sir I would propose to use Atmel328 chip . I have all components for a prototyping and debug of the deice here (except a pressure sensor, but it can be debugged remotely). Using of external EEPROM chip woill be necessary in any case to store 72K of the data. I have more than 20 years of experience in programming and electronics.

Hello, Sending you a bid for design and programming of a micro-controller circuit, It's according to the details you posted, Includes: - Design circuit diagrams - Design PCB board (layout ) - programming (I'm not including prototyping cost, if needed - please let me know.) I could recommend several controllers depending on the requirements you have for storage and interface ( removable storage ?, wireless...) send me a message and we can discuss in more detail. Regards, Nimrod.

Hi There, We will ship you fully working prototype packed in robust enclosure (we have seen the diagram where these sensor and electronics going to be used). We recommend to use pressure switch that indicates if the system is in working state. Further more we recommend to use AVR micro controller cloned in arduino (this will simplify the programming as arduino IDE is open source, programing language is C). It will be good enough if you use SD card for data logging (later on you can import CSV files in PC) and also we recommend to use RTC (real time clock, on board clock for date and time stamping). we will provide RS485 interface to connect the circuit with PLC. If all these looks fine feel free to contact us. Best Regards, Shahbaz.

Here are my comment - still not a proposal yet as we need to clarify many items. 1. It's better to go with ATmega328p. This also from Microchip but you'll be able to reuse a lot of libraries from Arduino which are quite mature now. Of course, language will be C++ (not C). 2. Reading temp. from LM35 or PT100 is not big deal. Just mainly ADC process and make sure VCC is well regulated to use as ref. voltage. 3. Honeywell PX2: It's difficult to get one here for testing. It's also expensive. Basically, the sensor output is current or voltage. If voltage output, just ADC. If current output, need an accurate resistor to convert to voltage - I may work with you to test remotely. 4. Storage can be on MicroSD card or serial flash chip such as w25q128 (16MB). 5. Real-time can be used common module such as DS3231. 6. About touch screen, keep in mind that it is resistive type (unfortunately, most modules use this) which is much worse than your smartphone screen. 7. Interface with PLC - not sure what you want. If just 1 or 0, one pin is enough. If something more than that, you'll need more pin or go with option such as: output data as serial ttl-rs232. With serial output, you can send a lot of info but your PLC needs the rs232 capability. I'll send a detail proposal once we clarify all the functionality. If you have any question, pls do not hesitate to chat. I am in Vietnam (UTC+7) so we can chat in early morning or evening. Thanks, Anh

Hi, I'm Ganapathy, I have done project on PIC, AVR and ARM , in C, C++ and Assembly. I summon your need in description - two temperature sensor - one pressure sensor so total of 3 ADC - one storage unit so microSD card interface - one display unit with touch screen but I need more than that - PIC16F have limited RAM so C++ is not feasible but I can implement oops (kind of) in c using functional pointer and structure . possible alternative AVR it can use Arduino which is C++ ide or ARM but it would be Overkill - pressure sensor starts a count down timer but what happens when it hit zero what task has to be done at the condition.? - does temperature sensor have threshold , i.e send a signal when cross over or below it? - if display only change color then why can't you just use a LED indicator or does the LCD display temperature and pressure values as well? contact me for more clarification Thank you
