However, people often neglect or fail to remember to collect the letters from the letter box. However, there can be a high possibility of missing important applications, notices, couriers, and letters if the person fails to check the letter box on time. This traditional letter box needs a person to regularly visit the letter box to check the letter box for any new letters, couriers, or mails. It may cause a time-wasting process and leads to negligence in some situations. Thus, there is a need for efficiently and effectively monitoring a letter box system with minimum human intervention.

The user of the letter box monitoring system can remotely check the status of any new letters dropped into the letter box using cloud and mobile application.
