It works on rainfall rate. When the rainfall is more then the wiper actuates very quickly. When the rainfall is slow it means the wiper moves slowly. According to intensity of rainfall the wiper works. it consists of sensors, actuators and cup and wiper mechanism . it has been proved working in Adams simulation and Pro E and Catia modelling. It is very useful in the automation field.
Selection and study of particular application of sensor.
Automated windshield wiper system.
Prepare demo setup.
Conductive transduction mechanism
ADVANTAGES OF WIPERS
Piezoelectric transduction mechanism
Optical transduction mechanism
Optical sensor works on concept of reflection and refraction.
At critical angle of incidence only reflection occurs.
PMMA 90 Prism
Phototransistor: QSD124 880nm wavelength
IR LED: QED223 AlGaAs 880nm
Resistor: 1K for Phototransistor; 910 for IR LED.
PCI DAQ 9024E
Mechatronic systems are best option for active safety systems.
Motor speed constant
LIMITATIONS OF WIPERS
Smaller sensitive area
Rain sensor is effective control system to replace manual wipers.
