8x8 pixel thermopile infrared array sensor module
The SMH-01B11 is a thermopile-type infrared array sensor module that can detect infrared energy in an 8×8 pixel area and convert it into radiative temperature output. It is equipped with a Si lens optical system, and through a built-in MCU with an A/D converter, it provides digital output of the converted radiative temperature for each pixel and the environmental temperature measured by the temperature sensor mounted on the sensor chip via an I2C interface. Additionally, it has a built-in variable gain preamplifier with magnification adjustable from 20 to 200 times, allowing for measurement across a wide temperature range with automatic range switching controlled by software. Compared to conventional sensors, it features high output sensitivity and a wide detection temperature range, and it is expected to be applied in home appliances, industrial equipment (air conditioning, medical, automotive), and healthcare solutions such as monitoring, medical care, and nursing.
