The EV3 Sensors give your robot information about the environment around it. The kit comes with multiple sensors that interact with the world around your robot in different ways and helps your robot decide how to respond to what it senses. You can use these sensors to avoid obstacles, trigger actions or find items.
- [Voiceover] There are a few other components…that come with the kit.…These transmit signals as invisible light…to further enable the EV3 robot.…Infrared light is invisible to the human eye…because it's wavelength is longer…than what we can see.…That means you won't be able to see infrared light…shining from the sensor or the remote beacon.…You just have to trust me that it's there.…This IR sensor can be used in one of three different modes.…In proximity mode, the sensor will emit…an infrared signal and detect its reflection off objects…to determine how far away an object is.…
The values returned range from zero meaning very close…to 100 meaning very far.…These values don't have units…such as centimeters or inches.…It's up to me to decide what a reading means…in my program.…Depending on the type of surface it's pointed at…the sensor can detect objects…up to 70 centimeters or 27 inches away.…The type of surface will greatly affect…the measurement from the IR sensor…because it can change how much of the infrared light…

Learn how to unpack the hardware, connect to the programming interface, run prebuilt programs, and control the motors and sensors. Chapter 6, "Adding Flow to a Program," covers advanced programming topics such as transferring data between blocks, using variables to store temporary data, programming conditional logic, and looping actions to run again and again. By the end of the course, you'll have the skills to bring your own robotic creations to life.
