Product Details

Si70xx/Si701x/Si702x Digital Humidity & Temperature Sensors

The Si70xx/Si701x/Si702x series of digital humidity & temperature sensors integrates a humidity sensor, temperature sensor, I2C 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 I2C 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.

Wide operating voltage range : 1.9 V to 3.6 V
Low power
I2C serial interface
On-chip heater
Great long term stability
Fully calibrated
Pre-installed protective filter
