Amrita Vishwa Vidyapeetham :

A group of engineering students at Amrita Vishwa Vidyapeetham in Kerala has developed a 'forest fire early detection system', via UAV and advanced computation technology, only to detect the fires at the early stage, and to get an instant alert with the help of GPS Location.

In making the system :

In making this system, the Kerala government’s forest & wildlife department has funded the money, which is successfully tested in Chambra Peak in Wayanad. This system's prototype is costing nearly about 25,000, which is currently used in the Wayanad district.

Newly developed forest fire alerts :

Most of the states across the country is using satellite-based forest fire alerts system. But this time the system which is developed by Amrita Vishwa Vidyapeetham can detect fires at the earliest stage and also can provide live streaming of the location through GPS.

Satellite-based forest fire alerts :

The used satellite-based forest fire alert system, in this system an imaginary satellite, used to take landscape photos of the affected region and relays them to the forest officials after a gap of two days. Which actually makes it difficult to stop the spreading of fire in the forest immediately.

Agni-Kavaj :

The system developed by that B.Tech students has given the name- ‘Agni Kavaj’. This system comprises a glider that carries two cameras, a video telemetry unit, a GPS module, a smoke sensor, and a micro-controller.

University statement :

According to the statement of the University, “If normal fire image is detected, the communication part is made active and in a smoky environment, the sensor part of the glider is made active to check the amount of carbon dioxide present in the atmosphere. Readings in smoke sensors are monitored and if the reading is above a particular threshold level, then the communication part is made active which sends alert messages of the fire location to forest officials”

It also says, “The second camera of the glider gives live streaming of the location to forest officials to avoid a false alarm.”

Forest inventory records :

Every year large numbers of forests used to get destroyed by fires of varying intensity and extent.

According to the forest inventory records, 54.40% of forests in India are exposed to occasional fires, 7.49% to moderately frequent fires, and 2.40% too high incidence levels while 35.71% of India’s forests have not yet been exposed to fires of any real significance.

In 2018, 37,059 fires detected via MODIS (Moderate Resolution Imaging Spectro-radiometer) sensor data.
