Sensors are devices that record the physical attributes of the environment around them. There are many types of sensors, for example, light and sounds sensors. Without sensors, we wouldn't be able to accurately record features of our physical surroundings, like maps or anything underground. We would no longer be able to scientifically predict the weather, study new types of medicine or chemical reactions. Law enforcement officers use radar to detect the speed of vehicles. Medical professionals use a pulse-oximeter to sense the amount of oxygen in the blood. Students using the TI Sensor Tag can record data about the temperature of the room, the light in the room, the humidity, movement relative to the TI Sensor Tag, and sound. The data that is collected by sensors can always be put into a chart for analysis. For instance, a device that collects data related to temperature can be put into a line chart because of the constant changing temperature which has an infinite amount of data points. A pie chart is used to visualize percentages within a whole. For example, if a sensor was being used to track heart rates over twenty-four hours, a pie chart could compare when the heart rate was high, low, or average. A bar chart compares different categories of data. For example, a bar chart could be used to compare humidity in different locations. Measuring environmental data, like studying effect of certain chemicals on a disease can help cure the disease and save lives. Weather balloons which have a variety of sensors on them are used to predict weather and prepare people for severe weather. Seismographs are used to measure earthquakes which can help save people from natural disasters.
