HX711 DIY Jewelry Digital Scale Kit For Arduino<br>HX711 module technical parameters:<br>HX711 is designed for high precision weighing sensor 24 A \/ D converter chip. Compared with the same type of other chip that integrates the peripheral circuits including power supply and on-chip clock oscillator which other similar types of chips needed.With high integration， fast response， anti-interference and other advantages.Reducing the overall cost of electronic scales and improve the overall performance and reliability.The chip and the MCU chip interface and back-end programming is very simple， all the control signals from the pin drivers， doesn't need to programming the registers of the chip.Input selector switch can be arbitrarily selected channel A or channel B， and is connected with its internal programmable low-noise amplifier.Channel A programmable gain is 128 or 64， corresponding to the full amount of the differential input signal amplitude is &amp;plusmn; 20 mV or &amp;plusmn; 40 mV.Channel B is fixed gain of 32 used for the system parameters detected.Chip provides regulated power supply can be provided directly to the external sensor and chip A \/ D conversion， the system board doesn't need additional analog power.The chip internal clock oscillator does not require any external devices.Automatic power on reset function simplifies the initialization process to boot.<br>Features:<br>Two selectable differential inputsProgrammable gain is 128 or 64Chip provides regulated power supply can be provided directly to the external sensor and chip A \/ D conversionThe chip internal clock oscillator does not require any external devices， if necessary， can also use an external crystal or clockAutomatic power-on reset circuitSimple digital control and serial communication: All are controlled by the input pin， the chip registers don't need programmingSelectable output data rate is 10Hz or 80Hz<br>Note: As the temperature， environment， wire and other factors， so the actual error is about &amp;plusmn;0.5g<br>Package included:<br>1 x HX711 weighing sensors for AD module1 x Mini three layers acrylic stand (with screw studs)1 x 5KG variable resistance sensors1 x 1602 I2C LCD display1 x 50G weights1 x 100G weights1 x Male to female dupont line1 x UNO R3 motherboard1 x USB cable
