Gravity Digital HX711 Load Cell 1Kg Weight Sensor Kit

The electronic Arduino weight sensor can recognize a weight of 1 kg and is based on the HX711, a 24-bit analog-to-digital converter for scales and industrial control applications. It uses the DFRobot Gravity Interface for easy connection, making it a good choice for electronics enthusiasts who want to build small scales for home use. 

Features: 

• Active low-noise on-chip PGA with selectable gain of 32, 64, and 128 
• On-chip power supply regulator for analog weigh-cell and ADC supply 
• On-chip oscillator requiring no external components, with optional external quartz 
• On-chip Power-on-Rest
• Easy digital control and serial interface: Pin-controlled controls, no programming required
• 16-pin SOP-16 package
