An Overview on Quantum dot technology in Temperature sensor design
Abstract: Quantumdot (QD) thermometry harnesses the sizedependent electronic structure of semiconductor nanocrystals to translate minute temperature variations into robust optical signals. In this work we present a systematic design framework for QDbased temperature sensors that integrates (i) bandgap engineering through precise colloidal synthesis, (ii) surfacestate passivation to suppress nonradiative pathways, and (iii) a planar photonicreadout architecture compatible with lowcost, CMOSfriendly fabrication. By exploiting the linear redshift of the photoluminescence (PL) peak …

Non-Invasive Glucose Monitoring Device Using Max30102 Sensor
Abstract: Diabetes mellitus is a chronic metabolic disorder affecting millions globally, requiring continuous blood glucose monitoring to prevent complications such as cardiovascular disease, kidney failure, neuropathy, and retinopathy. Conventional invasive finger- prick techniques result in pain, skin irritation, and an increased risk of infection, which lowers patient compliance, particularly in young patients and the elderly. This paper presents a non-invasive glucose monitoring prototype using the MAX30102 optical biosensor interfaced with the …

Arduino based Colour Sensing System with Real-time RGB Display on LCD
Abstract: Using a microcontroller Arduino UNO and TCS3200 color sensors, this project investigates the creation of a color measuring system. Colour sensors operate by emitting light onto an object and analyzing the reflected wavelengths to determine its colour. Our system is designed to detect a wide range of colours with high precision and display the corresponding Red-Green-Blue (RGB) values in real-time on a liquid crystal display (LCD). The TCS3200 sensor, developed …
