The SF-2 is based on the Texas Instruments High Accuracy Digital Humidity Sensor with Temperature Sensor, the HDC1010. It has a Relative Humidity Accuracy ±2% (typical) and a Temperature Accuracy ±0.2°C (typical) with 14-bit measurement resolution. Sleep mode current is 100nA. Supply current is710nA @ 1 sps, 11 bit RH Measurement and 1.3 μA @ 1 sps, 11 bit RH and Temperature Measurement. The supply voltage range is from 2.7V to 5.5V.It communicates using a 2-wire interface compatible with I2CTM. There are two jumpers that allow the user to select the senor address.

When purchased, additional information will be emailed to you including a Bill of Materials, pdf Schematic, board and Microchip datasheets, Altium schematic, Altium schematic and PCB libraries and example Arduino code.

The Arduino Code User interface has a help menu, allows you to set and get the configuration register, read Humidity and Temperature, get the manufacturers ID, get the device ID, get the unique serial number of the sensor.
