HX711 Weighing Pressure Sensor Module Big SizeModule main technical parameters:
Our HX711Load Cell Amplifieris a low cost A/D converter module incorporating a very high precision 24 bit ADC and differential high gain inputsthat allows you to easily read load cells,bridge sensors, pressure, strain and weight sensorsto measure weight. 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 used to create your own weight scale, process control, or simple presence detection.based on Avia Semiconductor's patented technology, HX711 is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to VCC analog power supply pin. Channel B has a fixed gain of 32. An on-chip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor. There is no programming needed for the internal registers. All controls to the HX711 are through the pins.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.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:Red (Excitation+ or VCC)Black (Excitation- or GND)White (Amplifier+)Green (Amplifier -)Yellow (Shield)
