A colorimeter is a laboratory device used to measure the absorbance of light at specific wavelengths in a given solution. Colorimetry is based on Beer-Lambert’s law, which states that the amount of light absorbed by a colored solution is directly proportional to the solution’s concentration and the length of the light path through it. When light passes through a sample solution, part of it is absorbed, while the remaining light is transmitted. By comparing the color intensity of a solute in the sample solution to that of a reference solution with a known solute concentration, we can estimate the concentration of the colored solute in the sample. Colorimeters are commonly used in fields such as water analysis, environmental analysis, and laboratory research.
Colorimeters, if accessible to households, could be used for practical applications like food quality control, water testing, and gardening. For instance, they could help ensure the freshness of fruits based on their color, test the purity of tap water, or analyze soil nutrients for home gardening. These applications could contribute to health, food safety, and environmental conservation efforts at a personal level.
Overview of the Project
We are developing a colorimeter using an RGB LED to produce a spectrum of wavelengths by adjusting the intensity of the red, green, and blue LEDs individually. The emitted light passes through a solution sample in a cuvette positioned between the LED and a light-dependent resistor (LDR). LDR is a special resistor which creates variying voltage drop across it based on the intensity of incident light. The solution absorbs specific wavelengths based on the solute’s concentration and nature of the solute. Unabsorbed light is incident on the LDR , where voltage variations are recorded to calculate the corresponding intensity of a particular wavelength and hence the intesity across the spectrum. The analysis is performed in a closed black box to eliminate the external light sources from disturbing the analysis. A Zero Analysis is performed with only the pure solvent (e.g., distilled water), prior to performing actual analysis by placing the sample of the solute. Then the difference between the actual analysis and zero analysis is taken. This significantly reduces the the external noise from other light sources and defects in the RGB leds which do not produce the exact wavelength.
The wavelength and light intensity of the light are then displayed on a 4-bit 7-segment display. To efficiently transfer data to the display unit and minimize the number of pins required, we are using a Serial-In-Parallel-Out (SIPO) shift register.
The “Ethical RISC-V IoT Workshop” at IIIT Bangalore, organized in collaboration with VSD, is a structured, educational competition aimed at exploring real-world challenges in IoT and embedded systems. Participants progress through three stages: building an application, injecting and managing faults, and enhancing application security. The event spans from May 9 to June 15, 2024, culminating in a showcase of top innovations and an award ceremony. This hands-on hackathon emphasizes learning, testing, and securing applications in a collaborative and competitive environment.

VSD Intern Webinars
VSD Interns made it happen !!
VSD is working towards creating innovative talent pool who are ready to develop design and products for the new tech world. VSD believes in “Learning by doing principle” , and always prepare the student to apply the knowledge learned in the workshops, webinars and courses. We always push our students to work on new designs, test it and work continuously till it becomes the best performing design. Any student who enrolls to VSD community starts working with small design and grows with us and develops a tapeout level design with complete honesty and dedication towards the Work !!
Welcome to the World’s only online conference in Semiconductor Industry VSDOpen Conference. With enormous support and global presence of audience from different segments of industrial lobby and academia made a highly successful event. Evolution is change in the genetic makeup of a population over time, online conference is one kind evaluation everyone adapt soon.
VSDOpen 2022 is an online conference to share open-source research with the community and promote hardware design mostly done by the student community.
VSDOpen 2022 is based on the theme “How to lower the cost to learn, build, and tapeout chips ?” , which will provide a platform to community to build stronger designs and strengthen the future of Chip design.
VSDOpen is envisioned to create a community based revolution in semiconductor hardware technology.
The open source attitude is required to bring out the talent and innovation from the community who are in remote part of world and have least access to the technologies. And now Google support will help to bring the vision to execution by VSD team.
