What does a HX711 do?

What is the HX711? The HX711 is a precision 24-bit analog-to-digital converter (ADC) that is designed for weighing scales and industrial control applications to interface directly with a bridge sensor. It is specially made for amplifying signals from cells and reporting them to another microcontroller.

What is HX711 ADC?

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, load cell & strain guages. It Interface with simple digital I/O to any controller.

What is the HX711 output?

HX711 is an ADC chip with preamplifier included. The chip is specifically designed for weight scales applications. These outputs are difficult to handle directly by controllers, so we can use HX711 IC which takes these voltage signals and provide standard digital values which can be used by a microcontroller.

Is HX711 an SPI?

The digital interface to the HX711 is a proprietary SPI-like interface that uses a clock (SCK) and data (DOUT) line.

How does a HX711 load cell works?

HX711 is a 24bit ADC, which amplifies and digitally converts the Load cell output. Then this amplified value is fed to the Arduino. Now Arduino calculates the output of HX711 and converts that into the weight values in grams and shows it on LCD. A push-button is used for calibrating the system.

Is the HX711 I2C?

It has all the features of the HX711 but with additional library support, a true I2C interface, and no soldering required! The HX711 uses a two-wire interface (Clock and Data) for communication.

How do I use HX711 as ADC?

How to use ADC?

1. To activate the on-chip oscillator, connect pin14 to ground. The output data rate is 10SPS or 80SPS. Use a crystal across XI and XO pins to obtain an accurate data rate at the output.
2. Pin11 and pin12 are used to retrieve data. The pin12 becomes HIGH, when data is not ready.

Is HX711 an I2C?

What is HX711?
