Pandemic since Covid-19 and currently due to Omicron has proven the importance of the health parameters like Heart Rate, Percentage Oxygen in the Blood and the Body Temperature; and is therefore universally known. Varieties of Pulse oximeters are available in the market at cheaper rates and mainly focus on the Heart rate and the percentage of oxygen in the blood while the body temperature is an equally important parameter and needs to be measured in emergencies. The pulse oximeters available in the market are not recommended by the medical doctors in emergencies so far the accuracy is a concern while the highly sophisticated and accurate pulse oximeters are too costly and are available only in ICUs and ICCUs in big hospitals. Here in this paper, an attempt is made to design the transmittance method-based pulse oximeter using a microcontroller which will measure not only the heart rate and the percentage of oxygen in the blood but will also measure the body temperature in ?C. Care is taken to meet the accuracy requirement with a reasonable cost to be recommended by the medical doctors in emergencies and can be made available even at small places due to low cost.
