All members of this device family combine fully factory-calibrated humidity and temperature sensor elements with an analog 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.

S E N S O R SOL UTIONS Humidity and Temperature Sensors www.silabs.com/humidity-sensor Si70xx Development Tools The Si70xx is supported by a suite of hardware and software development tools that facilitate testing/characterization, prototyping and software development. The Si7013USB-DONGLE Evaluation Kit comes with everything developers need to demonstrate and evaluate the Si7013. The board plugs into a PC via a USB socket. It has a connector for adding the Si7013/20/21-EB Daughter Cards. The Si7013, Si7020 and Si7021-EB (included with the Si7013USB-DONGLE) are three small daughter cards that permit evaluation of the Si70xx at the end of a flex cable. They plug right in to the USB-DONGLE if the user wants to put a sensor in a temperature/humidity chamber or a product prototype. The Si7013EVB-UDP is a small daughter card that permits evaluation of the Si7013 in conjunction with certain Unified Development Platform (UDP) components such as the C8051F960 8-bit and the SiM3L1xx LCD 32-bit Ultra-Low Power Microcontroller Development Kits. It plugs directly into UDP MCU cards for fast prototyping and software development. In addition to an on-board Si7013, there is a connector for adding an Si7013/20/21-EB via its flex cable, allowing the user to place the Si7013 in a temperature/humidity chamber or a product prototype. The Si7005EVB-UDP-F960 Development Kit and Si7013EVB-UDP-M3L1 Development Kit combines the 8-bit or 32-bit Ultra-Low Power Microcontroller Development Kits and the Si7013EVB-UDP daughter card with data logger demonstration code. It is a complete package designed to support hardware and software development using the Si7013 and Silicon Lab's ultra-low power MCUs. It ships with example software that implements a portable, battery-powered data logger/asset tracker.
