The light sensor is developed based on the principle of photoelectric effect of semiconductors. It can be used to detect the intensity of ambient light. It is usually used to create interactive projects that produce special effects with changes in light intensity, such as smart desk lamp robots, chasing robots, etc.
The PIR motion sensor is a sensor for detecting infrared radiation emitted by a human or animal body, and can be used for a variety of human or animal mobile triggering scenes.
The sound sensor can be used to detect the sound intensity in the surrounding environment. It can be used to interact with sound projects such as voice-activated robot.
The ultrasonic sensor is a module for detecting the distance between the obstacle in front and the module. It enables the robot to perceive the surrounding environment through the sonar like a bat. Through the control of the motor, the robot can automatically avoid obstacles.
The temperature and humidity sensor is a sensor that can be used to detect the ambient temperature and humidity. It can monitor the temperature and humidity changes in the surrounding environment.
The line follower sensor can help the robot to track white lines or black lines (black lines on a white background or black lines on a white background can be detected). The module has two infrared sensors with low delay and can detect the status of ground lines in real time.
This cymbal player is more than ready to play but lack of motivation. Give it some clapping and it will perform a 10-second cymbal playing!
Temperature and humidity sensor
This windmill has its own temper - it works only when it's about to rain.
