The contactless bell inside the Pashupatinath temple operates on ‘proximity sensor’ with which it is capable of detecting the presence of nearby objects without any physical contact. When there are objects near the technology-induced sensor, the bell rings automatically.
Nehru Khan says, just like the way they listen to azan, he wanted the clanging of the bells to be heard. Therefore, he installed this special kind of bell, that works on a sensor.
It is said that, Khan collected the sensor from Indore and created a machine at a factory cost of around ₹60,000.
