I need to design a new product, called Runtime Sensors for fuel. The project consists in build sensors to measure fuel quality and fuel level to be installed inside fuel tanks in fuel stations. The sensors cannot have ANY KIND of electronic to be installed inside tanks. All electrical and electronics must be outside, So, inside only mechanical stuffs and optical devices (like measure opacity and fuel level inside tanks, you can use a fiber optic inside the tanks and electronic will be installed outside). All the sensors must be controlled by a sigle controller and this controller must be able to comunicate through RS-485. Firmware must be a single firmware to be used as example. Also, the controller must have a display to show running measured parameters. Sensors must be made for three kind of fuels: ethanol, diesel and gasoline. Project can be splitted into steps different of the ones proposed, but milestones will be released ONLY ofter each step completed. No advance payment, anyway! So, please if you don't agree with this, please do not post a bid. P.S.: For each step concluded, payment will be released only after proof of conclusion. Proposed Steps: 1 - Sensors concept: Define every sensors and hardware to be used as controller; 2 - Board Layout: Design board with selected components; 3 - Board Prototype: Produce and assembly proposed board; 4 - Firmware Development: Write a basic software to run in the prototype; 5 - Test; 6 - Hardware and Software Adjust; 7 - Final Hardware and Software Delivery;

HI, I see your spec and have some questions relevant to the implementation of sensor. Please find these question on the private message I have development some sensor with this kind of application, really it is the first time with fuel, I designed sensors for water, acid, dust... I am sure to can do this project for you. just a little about milestone, freelancer ask in advance the 10% of bid to be payed by supplier, for that reason aI asked for a first milestone at the beginning, if you like we can found an alternative way.
