About the Practice
Problem Statement:

Alert when Mail Box gets Mail


Post box alarm is a device to sound an alarm as soon as something is dropped in a letterbox placed far away at the main gate of a large farm or housing premises. It has a light-spring-loaded flap fixed at the bottom of the letterbox. When the postman drops the day's mail, the flap is deflected and this is made to give out a pulse-alarm in the household. The alarm may be a short-duration hoot or light flash. Emptying the letterbox automatically resets the device.
