By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection of an object. 10 | 11 | The HX711 uses a two wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. 12 | 13 | Load cells use a four wire wheatstone bridge to connect to the HX711. These are commonly colored RED, BLK, WHT, GRN, and YLW. Each color corresponds to the conventional color coding of load cells: 14 | 15 | * Red (Excitation+ or VCC) 16 | * Black (Excitation- or GND) 17 | * White (Amplifier+, Signal+, or Output+) 18 | * Green (A-, S-, or O-) 19 | * Yellow (Shield) 20 | 21 | The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI (electromagnetic interference). Please keep in mind that some load cells might have slight variations in color coding. 22 | 23 | Repository Contents 24 | ------------------- 25 | 26 | * **/Production_Files** - Panelized version of the design for production 27 | * **/datasheets** - Datasheet for HX711 IC 28 | * **/firmware** - Example Arduino sketches 29 | * **/hardware** - All Eagle design files (.brd, .sch) 30 | 31 | Documentation 32 | -------------- 33 | * **[Library](https://github.com/bogde/HX711)** - Arduino library for the HX711 34 | * **[Getting Started with Load Cells](https://learn.sparkfun.com/tutorials/getting-started-with-load-cells)** - Introduction to Load Cells 35 | * **[Hookup Guide](https://learn.sparkfun.com/tutorials/load-cell-amplifier-hx711-breakout-hookup-guide)** - Basic hookup guide for the Load Cell Amplifier 36 | 37 | License Information 38 | ------------------- 39 | 40 | This design is [OSHW](http://www.oshwa.org/definition/) and public domain but you buy me a beer if you use this and we meet someday ([Beerware license](http://en.wikipedia.org/wiki/Beerware)). 41 | -------------------------------------------------------------------------------- /firmware/SparkFun_HX711_Calibration/SparkFun_HX711_Calibration.ino: -------------------------------------------------------------------------------- 1 | /* 2 | Example using the SparkFun HX711 breakout board with a scale 3 | By: Nathan Seidle 4 | SparkFun Electronics 5 | Date: November 19th, 2014 6 | License: This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). 7 | 8 | This is the calibration sketch.

After doing much research, communicating with our multiple fab houses, and getting quotes of various designs, we have compiled three DRU files. 1698 | <p> 1699 | <b>STANDARD:</b> This is more of a "best case scenario" set of limitations. If your design has the space, and/or you have the time to work within these parameters, please do. Larger trace width and clearance makes for easier visual inspection of the PCB while troubleshooting (useful in production and to the end user). It also allows for better ability to hack a trace (if you are crazy enough to scrape away the mask and solder to a trace). Another thing to keep in mind is that more metal is just more robust. 1700 | <p> 1701 | <b>TIGHT:</b> This is where cost comes into play. We have found that most fab houses begin to add extra charges when you go smaller than these specs. In some cases, going to less than 15 mil trace can increase the cost by 10%. (This is why we have set the min drill on this DRU to 15 mil) Same story for traces thinner than 7 mil. To avoid those extra charges, then stay within the rules of this DRU. 1702 | <p> 1703 | <b>FAB-LIMIT:</b> These set of rules are at the very limit of most fab houses capabilities. You will pay more for these specs, and it should be used on designs that have a darned good reason to need 4 mil vias and 4 mil traces. 1704 | <p> 1705 | **NOTE Clearance, Distance, Sizes, and Restring are all set to different limits in each of these three DRU files. Please compare the files within the CAM job editor window of eagle to see all the numbers. 1706 | <p> 1707 | ***NOTE, Please set your Net Classes to default (0mil for all settings), so that it won't effect the DRC when you run it with these settings. 1708 | 1709 | 1710 | 1711 | 1712 | 1713 | 1714 | 1715 | 1716 | 1717 | 1718 | 1719 | 1720 | 1721 | 1722 | 1723 | 1724 | 1725 | 1726 | 1727 | 1728 | 1729 | 1730 | 1731 | 1732 | 1733 | 1734 | 1735 | 1736 | 1737 | 1738 | 1739 | 1740 | 1741 | 1742 | 1743 | 1744 | 1745 | 1746 | 1747 | 1748 | 1749 | 1750 | 1751 | 1752 | 1753 | 1754 | 1755 | 1756 | 1757 | 1758 | 1759 | 1760 | 1761 | 1762 | 1763 | 1764 | 1765 | 1766 | 1767 | 1768 | 1769 | 1770 | 1771 | 1772 | 1773 | 1774 | 1775 | 1776 | 1777 | 1778 | 1779 | 1780 | 1781 | 1782 | 1783 | 1784 | 1785 | 1786 | 1787 | 1788 | 1789 | 1790 | 1791 | 1792 | 1793 | 1794 | 1795 | 1796 | 1797 | 1798 | 1799 | 1800 | 1801 | 1802 | 1803 | 1804 | 1805 | 1806 | 1807 | 1808 | 1809 | 1810 | 1811 | 1812 | 1813 | 1814 | 1815 | 1816 | 1817 | 1818 | 1819 | 1820 | 1821 | 1822 | 1823 | 1824 | 1825 | 1826 | 1827 | 1828 | 1829 | 1830 | 1831 | 1832 | 1833 | 1834 | 1835 | 1836 | 1837 | 1838 | 1839 | 1840 | 1841 | 1842 | 1843 | 1844 | 1845 | 1846 | 1847 | 1848 | 1849 | 1850 | 1851 | 1852 | 1853 | 1854 | 1855 | 1856 | 1857 | 1858 | 1859 | 1860 | 1861 | 1862 | 1863 | 1864 | 1865 | 1866 | 1867 | 1868 | 1869 | 1870 | 1871 | 1872 | 1873 | 1874 | 1875 | 1876 | 1877 | 1878 | 1879 | 1880 | 1881 | 1882 | 1883 | 1884 | 1885 | 1886 | 1887 | 1888 | 1889 | 1890 | 1891 | 1892 | 1893 | 1894 | 1895 | 1896 | 1897 | 1898 | 1899 | 1900 | 1901 | 1902 | 1903 | 1904 | 1905 | 1906 | 1907 | 1908 | 1909 | 1910 | 1911 | 1912 | 1913 | 1914 | 1915 | 1916 | 1917 | 1918 | 1919 | 1920 | 1921 | 1922 | 1923 | 1924 | 1925 | 1926 | 1927 | 1928 | 1929 | 1930 | 1931 | 1932 | 1933 | 1934 | 1935 | 1936 | 1937 | 1938 | 1939 | 1940 | 1941 | 1942 | 1943 | 1944 | 1945 | 1946 | 1947 | 1948 | 1949 | 1950 | 1951 | 1952 | 1953 | 1954 | 1955 | 1956 | 1957 | 1958 | 1959 | 1960 | 1961 | 1962 | 1963 | 1964 | 1965 | 1966 | 1967 | 1968 | 1969 | 1970 | 1971 | 1972 | 1973 | 1974 | 1975 | 1976 | 1977 | 1978 | 1979 | 1980 | 1981 | 1982 | 1983 | 1984 | 1985 | 1986 | 1987 | 1988 | 1989 | 1990 | 1991 | 1992 | 1993 | 1994 | 1995 | 1996 | 1997 | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | 2035 | 2036 | 2037 | 2038 | 2039 | 2040 | 2041 | 2042 | 2043 | 2044 | 2045 | 2046 | 2047 | 2048 | 2049 | 2050 | 2051 | 2052 | 2053 | 2054 | 2055 | 2056 | 2057 | 2058 | 2059 | 2060 | 2061 | 2062 | 2063 | 2064 | 2065 | 2066 | 2067 | 2068 | 2069 | 2070 | 2071 | 2072 | 2073 | 2074 | 2075 | 2076 | 2077 | 2078 | 2079 | 2080 | 2081 | 2082 | 2083 | 2084 | 2085 | 2086 | 2087 | 2088 | 2089 | 2090 | 2091 | 2092 | 2093 | 2094 | 2095 | 2096 | 2097 | 2098 | 2099 | 2100 | 2101 | 2102 | 2103 | 2104 | 2105 | 2106 | 2107 | 2108 | 2109 | 2110 | 2111 | 2112 | 2113 | 2114 | 2115 | 2116 | 2117 | 2118 | 2119 | 2120 | 2121 | 2122 | 2123 | 2124 | 2125 | 2126 | 2127 | 2128 | 2129 | 2130 | 2131 | 2132 | 2133 | 2134 | 2135 | 2136 | 2137 | 2138 | 2139 | 2140 | 2141 | 2142 | 2143 | 2144 | 2145 | 2146 | 2147 | 2148 | 2149 | 2150 | 2151 | 2152 | 2153 | 2154 | 2155 | 2156 | 2157 | 2158 | 2159 | 2160 | 2161 | 2162 | 2163 | 2164 | 2165 | 2166 | 2167 | 2168 | 2169 | 2170 | 2171 | 2172 | 2173 | 2174 | 2175 | 2176 | 2177 | 2178 | 2179 | 2180 | 2181 | 2182 | 2183 | 2184 | 2185 | 2186 | 2187 | 2188 | 2189 | 2190 | 2191 | 2192 | 2193 | 2194 | 2195 | 2196 | 2197 | 2198 | 2199 | 2200 | 2201 | 2202 | 2203 | 2204 | 2205 | 2206 | 2207 | 2208 | 2209 | 2210 | 2211 | 2212 | 2213 | 2214 | 2215 | 2216 | 2217 | 2218 | 2219 | 2220 | 2221 | 2222 | 2223 | 2224 | 2225 | 2226 | 2227 | 2228 | 2229 | 2230 | 2231 | 2232 | 2233 | 2234 | 2235 | 2236 | 2237 | 2238 | --------------------------------------------------------------------------------
