Single-Chip Relative Humidity and Temperature Sensors

Silicon Labs’ Si70xx state of the art relative humidity and temperature sensors utilize proven techniques for measuring humidity using polymer dielectric film along with CMOS mixed signal integrated circuits. These monolithic ICs combine fully calibrated humidity and temperature sensing elements, an I2C or PWM interface and on-chip signal conditioning into a compact, rugged and reliable package.
