Done by Group: Bayan_Poly4 School: Al Bayan Sec. School Module Polymers: Through this module, students examine the different properties of the variety of polymers. Then they design and test a humidity sensor made of a polymer film. Finally, they are asked to design their own products. This project: White Canes Motion Detector PVDF motion detector (polymer), it detects motion and its range is 8 meters with 60 degree around it. Also, Polyvinylidene Floride polymer sensor inside it So it detects heat.
