Aim
The aim of the project is to turn ON/OFF the calling bell automatically.
Problem statement
we are implementing Touchless Door Bells, which will lessen physical contact and sense the stranger’s distance and temperature so that the owner can be alerted that someone has arrived.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Brain Board
Output: Buzzer
Battery: Lithium-ion rechargeable battery
Component description
IR Proximity Sensor
The function of IR Proximity sensor is to detect the objects within 20CM and send the signal to the Brain unit (TinkerSpace board).
Buzzer
The function of the Buzzer is used to produce alert/alarm sound.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor IR Proximity Sensors and control the Buzzer.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case – 1: When a person is detected near the door, the IR proximity sensor (input) turns ON and sends signal 1 to the TinkerSpace sensor board (brain).The sensor board turns ON the buzzer (output).
Case – 2: When no person is detected, the IR proximity sensor turns OFF.Hence the sensor board turns OFF the buzzer.
IR proximity sensor ON —> Buzzer ON
IR proximity sensor OFF —> Buzzer OFF
