Aim
The aim of the project is to build a wiper which turns ON automatically during raining.
Problem statement
Sometimes heavy rainfalls occur, blurring the driver’s vision, which might result in serious accidents. It won’t be always practical for the driver to monitor everything. The driver has to keep an eye on the wiper which might distract him from driving. This issue can be resolved by installing a smart wiper which turns on and off automatically
Material used
Input: Rain Sensor
Brain: TinkerSpace Brain Board
Output: Servo Motor
Battery: Lithium-ion rechargeable battery
Component description
RAIN SENSOR
The function of Rain sensor is to detect the rain and send the signal to the Brain unit (TinkerSpace board).
SERVO MOTOR
The function of the servo motor is to turn on the wiper during raining.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor Rain sensor and control servo motor.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case – 1: When the rain is detected, the rain sensor (input) turns ON and sends signal 1 to the TinkerSpace brain board (brain). The sensor board oscillates the wiper with the servo motor (output).
Case – 2: When no rain is detected, the rain sensor turns OFF and sends signal 0 to the TinkerSpace brain board. The sensor board stops the
oscillation of the wiper.
Rain sensor ON —> Oscillate +/- 30°
Rain sensor OFF —> Angle 0°
