SENSOR SOLUTIONS www.silabs.com/humidity-sensor Humidity and Temperature Sensors FEATURES Precision Relative Humidity Sensor: Si7013/21: 3% RH (maximum) 080% RH Si7020: 4% RH (maximum) 080% RH Temperature Sensor: 0.4 C accuracy (maximum) -10 to +85 C Auxiliary 2nd zone sensor input (Si7013) 0 to 100% RH operating range Up to -40 to +125 C operating range The simpler, greener way to measure relative humidity Wide operating voltage range (1.9 to 3.6 V) Low Power Consumption: 1.9 W average power at 3.3 V and 1 sample per second 2 2 I C host interface DIGITAL I C HUMIDITY AND TEMPERATURE SENSORS Integrated on-chip heater The Si701x/2x devices are Silicon Labs 2nd generation family of relative humidity and 3 mm x 3 mm DFN package temperature sensors. All members of this device family combine fully factory-calibrated Excellent long term stability humidity and temperature sensor elements with an analog to digital converter, signal Factory calibrated 2 processing and an I C host interface. Patented use of industry-standard low-K polymer Optional factory-installed filter/cover dielectrics provides excellent accuracy and long term stability, along with low drift and low Lifetime protection during reflow and hysteresis. The innovative CMOS design also offers the lowest power consumption in the in operation industry for a relative humidity and temperature sensor.

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 Labs ultra-low power MCUs. It ships with example software that implements a portable, battery-powered data logger/asset tracker.
