• Sound Sensor: The sound sensor is based on a microphone to detect the intensity of sound in the surrounding environment
• Light Sensor: The main component of this sensor is a phototransistor and it can be used to detect the intensity of ambient light
• Temperature and Humidity Sensor: It detects changes in temperature and humidity in the surrounding environment
• Color Sensor: This sensor can also be used as a grayscale sensor to identify the grayscale of the color
• Line Follower: It can help the robot to track white lines or black lines

The Sensor Package a from Q Tronics includes one sound sensor, one light sensor, one temperature and humidity sensor, one color sensor, one PIR sensor, one gyroscope sensor, and one line tracking sensor.
