3-axis magnetic sensor which incorporates magneto-impedance (MI) elements to detect magnetic field and a control IC in a small package. The MI sensor features significantly lower current consumption and noise compared with conventional methods, making it suitable for not only for standard ecompass applications but sets requiring even higher accuracy as well.
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.
