Sensor

Author: Dr. K. S. Kang

Suchitra, due to advancing age was finding it difficult to ascend the stairs to go to the first floor of her house, in order to check that water tank is not overflowing. So as to avoid water wastage and inconvenience of climbing the stairs repeatedly, somebody suggested her to install a Water Sensor or tank alarm, that gave warning in English as well as in Hindi to switch off the water pump the moment the overhead tank was full. One day Suchitra left her house for her regular visit to her beautician. At that time as power was not coming so in hurry she forgot to put off the alarm and the water pump. As she was enjoying her facial, pedicure and other such processes at the Beautician, the power returned and the water pump along with the sensor alarm became active. After some time the water alarm started blaring, giving suggestions in two language to switch off the water pump but Suchitra was busy in beauty parlour for a couple of hours. Soon water started overflowing and the mixing of the sounds of alarm and the water falling from the roof was producing a strange symphony, unheard of even in the world of music.

Soon people collected before her house and were wondering at the strange mixture of sounds coming out of the locked house. Some were of view that some burglar had entered the house and he has been fatally injured and is in the last moments of his life. Some thought of the evil spirit that might have haunted the house and making strange noises in the empty and locked house, perhaps feeling lonely without the incumbent of the house. A few enterprising people even thought of breaking into the house so as to know the cause of this strange symphony coming out of the house, while a few elders cautioned these people not to go into the house unarmed as the hiding person may have some lethal weapon and harm them.

While these discussions were on Suchitra took turn to the street leading to her house and was amazed to see a crowd before her house. At first she thought that she might have forgotten to lock her house in her hurry to visit beautician, but key was with her and key come out of the lock only when it is properly locked. As she approached her house she heard the noise of water falling from the tank and the sensor alarm of the water tank getting hoarse after blaring the warning umpteen times. She understood the matter at once and through the crowd she marched ahead and opening the lock of her house went straight and put off the switch of the Sensor alarm and water pump. After some time water also stopped flowing bringing everything to normalcy. As the crowd saw the return of normalcy, they dispersed after some time.
