Dear Valued Employer, My name is Martin and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer who would be capable of designing a circuit for controlling the speed of a motor based on decrease/increase of ambient temperature. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion. 2. Proposal for solution. 3. Schematic draft based on proposed solution. 4. Feedback and discussion. I messed around with the task and it can be solved pretty neatly with a simple 555 timer, an output transistor which turns on/off the fan and of course a temperature sensor - PT100 in your particular case. And don't forget to add a diode for back EMF protection across the fan. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards, Martin K.

Hello, the project can be done cost effectively as you want, using the sensor and 1 or 2 IC what is the size of the dc motor you would drive? do you need to reverse direction? a single day is enough, if you need to build the setup and live show it will take a week
