• Light Sensor - measures brightness and allows Bittle to follow a light source. Employs two analog input pins in the Grove connector. 
• Touch Sensor - includes two touch pads and works as a simple keyboard. Employs two digital input pins in the Grove connector.
• Gesture Sensor - enables the robot to recognize simple top, down, left, and right gestures, making it possible to perform tricks. Employs the Grove connector 12C pins (SCL/SDA).
• PIR Motion Sensor - enables a robot to recognize the movement of a warm object, such as your hand, and makes Bittle capable of guarding a room. It employs one digital input pin for the Grove connector.
• Infrared Distance Sensor - enables a robot to detect the distances to the front obstacles on both sides. Employs two analog input pins in the Grove connector. 

Sensors are key to developing robotics solutions for IoT and AI applications with legged robots.  Our affordable sensors can integrate with Arduino, ESP32, and Raspberry Pi and their robotics kits and are great for robotics education, school projects, robotics camps and robotics classes.

Demo codes for optional sensor modules are available in Petoi's GitHub repository under the ModuleTests folder.

Detailed instructions and demo codes are available in our doc center.
