Working Principles

The working principle of temperature sensors varies depending on the type of sensor used. However, most temperature sensors rely on the fundamental property that certain physical characteristics of materials change with temperature.

  • Thermocouples work based on the Seebeck effect, where a voltage is generated across the junction of two dissimilar metals in response to a temperature gradient.

  • RTDs utilize the temperature-dependent change in electrical resistance of pure metals.

  • Thermistors use the temperature sensitivity of semiconductor materials to measure temperature.

  • IR temperature sensors detect and measure the thermal radiation emitted by objects, converting it into temperature values.

Applications of Temperature Sensors:

 Weather Forecasting: Temperature sensors play a crucial role in weather monitoring and forecasting. By collecting temperature data from various locations, meteorologists can analyze weather patterns, predict climate changes, and issue accurate forecast.

Medical and Healthcare: Temperature sensors are used extensively in medical applications, including thermometers, patient monitoring systems, incubators, and laboratory equipment. Accurate temperature measurement is essential for diagnosis, treatment, and research purposes

Food Industry: Temperature sensors are used for food safety and storage, ensuring perishable goods are stored at the right temperatures.

HVAC (Heating, Ventilation, and Air Conditioning): They help regulate indoor temperature for comfort and energy efficiency.

In research and development, temperature sensors enable scientists and engineers to conduct experiments, study material behavior, and innovate new technologies by providing precise and reliable temperature data.

Temperature sensors, often overlooked but omnipresent, silently contributeto the smooth functioning of various aspects of our lives. From weather forecasting to industrial processes, healthcare to automotive applications, these invisible thermometers are indispensable. As technology continues to advance, temperature sensors are becoming more accurate, compact, and integrated into our daily lives. With their ability to measure and monitor temperature changes, they ensure optimal conditions, improve efficiency, and enhance safety.

About Makershala

Makershala is a Learning by Making ecosystem for kids from age 8-16 to help them discover their interests, develop future skills and deepen conceptual understanding. Makershala follows the Project Based Learning approach as its way of teaching in which kids work on authentic, real life & personally meaningful projects.

Kids work on these projects in different educational settings, namely; self-learning; online 1:4 Peer to Peer with a mentor; or in a school. Projects are categorized in different interest segments like Robotics, Coding, Electronics, 3D Printing, Animations, Photography, Machine Learning, Astronomy and many more.

Each project is mapped with classroom concepts, 21st century skills, UN sustainable development goals and interests/careers to not only focus on holistic development of a child but help them identify their calling by giving them exposure to problems that exist in the real world.

Why Project-Based Learning

Project-Based Learning has the potential to solve many of the learning problems we see today beyond foundational literacy.

  • Ownership: Learners have complete ownership on what they need to know to solve a problem and come up with the best solution in the best way. It can be a concept or a software tool or a skill. Kids involved in projects are never required to be told to study.

  • Interdisciplinary: Unlike traditional learning where subjects are taught in silos and learners develop a perception of liking or disliking a subject. In project based learning, the given problem is supreme and it may require to know something from maths, science and history together.

  • Experiential learning: We generally retain 75% of what we do as opposed to only 5% of what we hear and 10% of what we read, hence PBL helps kids retain what they learn.

  • Lifelong learning: The most important gift that PBL gives to its learners is to make them lifelong learners as this is the most required skill to lead a good life, personally & professionally.

  • Skills & Knowledge balance: Project-based learning doesn’t focus too much on memorizing information, rather it equally demands practising life skills to be able to do better in projects.

How Makershala Works

  • Parents and Kids who wish to start their journey with Makershala, are suggested to pick one interest area of the child and then choose a plan.

  • Parents and Kids after enrolling in a course based on their interest are assigned a batch. Each batch has 3-4 learners and 1 mentor.

  • Each course has 6 guided projects and 1 challenge project.

  • During the project, formative assessments are conducted to evaluate learner’s knowledge & skills.

  • On completion of a project parents and kids get a learning report which indicates the skills and knowledge developed/displayed by them.

  • Kids also build their portfolio which showcases problems solved, solutions created, skills developed, knowledge acquired and technologies learnt.

  • Kids earn rewards in the form of badges, points and coins for their performance in a project, course and overall.

  • Kids are maneuvered to take up courses and projects from different learning segments to gain more clarity on their interests. This eventually helps them in picking up a career.
