Please apply only if you have experience in this type of work. This is a remote project for technicians who has had exposure to CMOS or CCD/PRISM/LED/ sensor systems, and have the capability to build the sensor assembly. We are a startup company looking at building a Refractometer Sensor Assembly (3 sensor assemblies for our prototype). The sensor will be integrated with a PCB, which will have other sensors. The purpose of the sensor assembly is to converts the refractive index of a food sample to % brix. OUR SPECS are as follows: The sensor assembly - must not exceed 20mm x 25 mm x 15mm in size - CMOS or CCD sensor - Triangular prism (see picture) - LED wavelength of about 600nm OTHER SPECS - 0 - 20 degree brix minimum - Precision ±0.1%; - Resolution 0.05% - Output Method: Digital - Sensor assembly must be calibrated and fully tested for correct reading. Important: We only need the sensor assembly and a microcontroller. So the deliverables are: - Sensor assembly, - source files, - Gerber files, - firmware, - Circuit and - CAD files Our budget is $1,000 payable only when the project is successfully completed Payment will be issued after work completed

Hi Employer! I am excited to submit my bid for the development of the Refractometer Sensor Assembly for your startup company. With my experience in CMOS and CCD/PRISM/LED sensor systems, I am confident in my ability to meet your project requirements. I understand that the sensor assembly should not exceed 20mm x 25mm x 15mm in size and must include a CMOS or CCD sensor, a triangular prism, and an LED with a wavelength of approximately 600nm. Additionally, it should convert the refractive index of food samples to % brix with a range of 0-20 degrees, a precision of ±0.1%, and a resolution of 0.05%. The output method should be digital, and the sensor assembly needs to be calibrated and fully tested for accurate readings. As per your request, the deliverables will include the sensor assembly, source files, Gerber files, firmware, circuit design, and CAD files. I have the necessary skills and expertise to develop these deliverables and ensure their quality. I am excited to collaborate with your team remotely and bring this project to fruition. Thank you for considering my bid, and I look forward to discussing the project details further with you.
