HX711 24-bit ADC module for load cells and pressure sensors with shielding

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
HX711 Red Board with Shielding is a high resolution amplifier and ADC module designed for load cells, weighing cells and other bridge type pressure sensors. The module uses the HX711, a 24-bit analog to digital converter specially designed for electronic scales and accurate force measurement.

The HX711 provides two analog differential channels. Channel A has programmable gain settings of 32, 64 or 128 times, while channel B has a fixed gain of 32 times. This makes the module suitable for measuring the very small voltage changes generated by a load cell when a load is applied.

A typical four wire load cell can be connected to E+, E-, A+ and A-. The HX711 provides excitation for the load cell and measures the differential signal from the sensor. The amplified signal is then converted into a digital 24-bit value that can be read by an Arduino, ESP32 or other microcontroller.

The board includes metal shielding to help reduce electrical interference affecting the sensitive measurement signal. This is particularly useful because the signal from a load cell is normally only a few millivolts. The board also includes capacitors for stable operation, built-in pull-up resistors and connection options suitable for different installation and soldering requirements.

The HX711 includes an internal voltage regulator and clock oscillator, reducing the need for external components. Data is transferred through two digital signals, normally referred to as DAT and SCK. No separate SPI or I2C bus is required.

The module can be used for digital scales, platform scales, force measurement, load measurement, pressure measurement and other sensor applications using bridge type sensors. It is also suitable for custom projects using Arduino and ESP32.

The board also provides reserved space for additional electronics, which can be used for further development of sensor related applications.
