Silicon Labs Temperature & Humidity Sensor, Digital Output, Surface Mount, Serial-I2C, ±1 °C, ±5%RH, 6 Pins

Si70xx/Si701x/Si702x Digital Humidity ; Temperature Sensors. The Si70xx/Si701x/Si702x series of digital humidity ; temperature sensors integrates a humidity sensor, temperature sensor, I ;sup>2 ;/sup>C serial interface, calibration and on-chip signal conditioning in one compact QFN/DFN CMOS package. When air comes into contact with the exposed polymide sensor, moisture in the air causes a capacitance change in the sensor resulting in the on-chip conditioning converting this to a humidity reading. This is then made available to the user over the I ;sup>2 ;/sup>C interface. Applications include asset and goods tracking, laptops, tablets, PLC and I/O modules, smart phones, thermostats, humidistats, wireless sensing, detection of gas, fire, smoke and water, ventilation and air conditioning. Features; Wide operating voltage range : 1.9 V to 3.6 V Low power I ;sup>2 ;/sup>C serial interface On-chip heater Great long term stability Fully calibrated Pre-installed protective filter
