What were the major technological changes introduced during the Sultanate period? How did those technological changes influence the Indian society?
In short
The Sultanate spread the geared Persian wheel, canals, the charkha and carding bow, paper, the true arch and dome, and new cavalry gear, which expanded cultivation, crafts, towns and a Persian-literate bureaucracy. Lime mortar enabled the true arch of Balban's tomb and the true dome of the Alai Darwaza (1311).

Gearing for water
The geared Persian wheel spread in the Punjab and the Doab, and Firuz Shah Tughlaq's canals carried Yamuna water to Hisar.
Charkha and carding bow
The spinning wheel appears in Indian sources by the 14th century, and the dhunia's carding bow cleaned cotton faster, raising yarn output over the hand spindle.
Paper
Paper replaced palm leaf and birch bark for records.
Building and cavalry
Lime mortar enabled the true arch of Balban's tomb and the true dome of the Alai Darwaza (1311), while the iron stirrup and horseshoe aided Turkish cavalry.
Agrarian growth
Irrigation extended cultivation and swelled the revenue feeding the iqta system.
Artisans and towns
A textile boom expanded weaver groups such as the julahas, the community of Kabir.
Literate bureaucracy
Cheap paper drew Kayasthas into Persian revenue offices.
Limits
Many devices had older Indian roots, spread was uneven, and gains went mainly to the state and towns.
Living lessons
Conserving the Qutb complex and Lodi-era baolis keeps this engineering legible and its water wisdom usable.
