Low cost IR imager from lapis semiconductor
The ML8540WD is a medium-resolution (approximately 2,000 pixels) infrared image sensor that allows noncontact temperature measurement of an object and easy obtaining of thermal images.
The ML8540WD receives infrared rays from an object at 48×47 (2,256) pixels resolution, converts them into voltage through a thermopile, and selects pixels in accordance with external CPU clocks to output signals. The built-in op-amp circuit amplifies the infinitesimal voltage of the thermopile for conventional output signal level. Furthermore, the temperature sensor circuit is used to output a temperature-compensated signal by measuring the chip temperature.
