Abstract
A sensor includes a first sensor transistor receiving external light and generating a first sensing current based on an amount of the received external light, a first capacitor storing a first sensing voltage based on the first sensing current from the first sensor transistor, a second sensor transistor receiving external heat and generating a second sensing current based on an amount of the received external heat, a second capacitor storing a second sensing voltage based on the second sensing current from the second sensor transistor, a light blocking member blocking the second sensor transistor from external light, and an opening exposing the first sensor transistor to external light.
