Grove - ADC module for load cell (HX711) / weight measurement

Grove - ADC for load cells (HX711)

The Grove - ADC for load cells (HX711) is a 24-bit A/D converter specifically designed for load cells. The module is designed to save you time (no soldering required) and simplify the use of load cells based on the HX711. 

It includes a low-noise programmable on-chip amplifier with an optional gain of 32, 64 and 128. The HX711 chip integrates a regulated power supply, an on-chip clock oscillator and other peripheral circuits that offer the advantages of high integration, fast response and strong anti-interference.

With the Grove connector and 4-pin screw terminal, it is easy to connect the load cell and the microcontroller without the need for soldering. You can build your own Arduino weighing sensor system in just a few simple steps.

What is the HX711?

The HX711 utilizes AVIA Semiconductor's patented integrated circuit technology. It is a 24-bit A/D converter chip designed for high-precision electronic scales. This chip offers the advantages of high integration, fast response time and strong noise suppression, which reduces cost and improves scale performance and reliability.

Features

• Fast response: output stabilization time up to 50 ms at RATE = DVDD and up to 400 ms at RATE = 0
• Strong interference suppression: Simultaneous suppression of 50 Hz and 60 Hz current interference.
• Customizable gain: It includes an integrated, low-noise, programmable amplifier with an optional gain of 32, 64 and 128.
• Grove unit plug-in system: The product ensures "plug and play" and can be used in a variety of applications.

Application

• Electronic scales
• Price computing scales
• Electronic platform scales
• Digital scales
• Parcel post scales
