SF-2 Humidity Sensor
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.

SF-7 Current Sensor

SF-7 Current Sensor

The SF-7 is based on the Texas Instruments INA138 High-Side Measurement Current Shunt Monitor. It has a maximum input voltage of 36V and is designed to measure currents between 10mA and 500mA. It uses a 0.1-ohm sense resistor and has a transimpedance gain of 4V/A. An antialiasing filter of 15.4khz is placed after a unity gain buffer that feeds a Texas Instruments ADC121C027 12-bit analog to digital converter. There is one jumper that allows the user to select between three addresses. The ADC reference is connected to VDD so the resolution is based on the voltage applied to the device. It communicates using a 2-wire interface compatible with I2CTM which supports Standard (100kHz), Fast (400kHz), and High Speed (3.4MHz) Modes. It has an out of range alert flag readable as part of the conversion register.

SF-1 Temperature Sensor

SF-1 Temperature Sensor

The SF-1 is based on the Microchip TCN75 2-Wire Serial Temperature Sensor. It has a resolution of ±1°C from -40°C to +125°C.  The resolution can be set, by the user, to one of 4 selections from 0.5°C to 0.0625°C.  The input voltage can be between 2.7V and 5.5V.  It communicates using a 2-wire interface compatible with I2CTM.  There are three jumpers that allow the user to select the sensor communication address. Typical power consumption is 200 µA.
