Instructions

  1. Pick a sensor from this list:

  • TCS34725 Color Sensor

  • BME280 (or BME680) Environmental Sensor

  • KY-037 Microphone Sound Sensor Module

  • AS5600 Magnetic Rotary Encoder

  1. Find the datasheet on the web for your chosen sensor

Question 1

Answer the following:

  • What does this sensor measure, and where could it be used?

Solution

TCS34725

Measures red, green, blue, and clear light levels. Used in line-following robots, color-sorting machines, and ambient light detection.

BME280/BME680

Measures temperature, humidity, and barometric pressure (BME680 also measures air quality VOCs). Useful in weather stations, drones (altitude), and HVAC monitoring.

KY-037

Detects sound levels or captures audio waveform. Used for clap-activated switches, voice detection, or audio input.

AS5600

Measures angular position of a rotating shaft (0-360°). Used in motor control, robotics joints, knobs, and steering systems.

Question 2

Answer the following:

  • Describe the working principle of the sensor. In other words explain the physical principle or technology it uses.

Solution

Solution is locked

Question 3

Answer the following:

  • How does the sensor communicate its data to a microcontroller?

Solution

Solution is locked

Question 4

Answer the following:

  • What are the alternatives to this sensor?

  • In what ways do they differ?

Solution
