HX 711 Module

HX711 module also known as Load Cell Amplifier breakout board designed for the HX711 IC. This IC allows you to easily read load cells to measure weight and load cells can be easily integrated into your project. HX711 module uses 24-bit high precision A/D converter chip HX711, with two analogue input channels, the internal integration of 128 times the programmable gain amplifier. These modules are designed specifically for the high precision electronic scale design in which an input circuit is configured to provide a bridge type pressure bridge (such as pressure, weighing sensor mode),

HX711 is an IC that eliminates the use of any amplifiers or dual power supplies. We need to just use this board and you can easily interface it to any micro-controller to measure weight. The HX711 uses a two-wire interface (Clock and Data) for communication. HX711IC features high integration, fast response, immunity, and other features improving the total performance and reliability. The Load cells are connected to the HX711 via a four-wire Wheatstone bridge. These are commonly coloured as RED, BLK, WHT, GRN, and YLW. Here the YLW pin normally acts as an optional input that does not hook up to the strain gauge; whereas utilized to the ground and act as a shield against outside Electromagnetic Interference.

• Red (Excitation+ or VCC)
• Black (Excitation- or GND)
• White (Amplifier+, Signal+, or Output+)
• Green (A-, S-, or O-)

This Load Cell Amplifier breakout board for the HX711 IC features high precision, low cost, high reliability making it an ideal sampling front-end module.  Thus used for a wide variety of applications creating your own industrial scale, process control, or simple presence detection.
