Silicon Labs Si7013/20/21 Relative Humidity and Temperature Sensors

The Si701x/2x devices are Silicon Labs' second generation family of relative humidity and temperature sensors.

  • 0 to 100% RH operating range
  • Up to -40 to +125 °C operating range
  • Wide operating voltage range (1.9 to 3.6 V)
  • Low Power Consumption: 1.9 μW average power at 3.3V and 1 sample per second
  • I²C host interface

Product Description

The Si701x/2x devices are Silicon Labs' second generation family of relative humidity and temperature sensors.
All members of this device family combine fully factory-calibrated humidity and temperature sensor elements with an analogue to digital converter signal processing and an I2C host interface.

Patented use of industry-standard low-K polymer dielectrics provides excellent accuracy and long term stability along with low drift and low hysteresis.
The innovative CMOS design also offers the lowest power consumption in the industry for a relative humidity and temperature sensor. Designers will appreciate the unique set of features offered by the Si701x/2x family.

With full factory calibration Si701x/2x devices require no additional RH/temperature calibration during PCB assembly. For protection against dust dirt and chemical contaminants during PCB reflow and during device operation all members of the Si701x/2x family can be fitted with an optional factory-installed cover.
In addition designs that require two-zone temperature sensing will benefit from the Si7013's auxiliary sensor input with programmable linearisation.

Relative Humidity Sensor

Si7013/21: ± 3% RH (maximum) @ 0-80% RH; Si7020: ± 4% RH (maximum) @ 0-80% RH.

Temperature Sensor

±0.4 °C accuracy (maximum) @ -10 to +85 °C.
