4pcs Load Cell 50kg Half Bridge Strain Gauge Human Body Digital Scale Weight Sensor 1pc HX711 Amplifier AD Module for Arduino DIYmalls

HX711 AD Module This module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale designwith two analog input channelthe internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge type pressure bridge (such as pressureweighing sensor mode)is of high precisionlow cost is an ideal sampling front-end module. Features: Two selectable differential input channels On-chip active low noise PGA with selectable gain of 3264 and 128 On-chip power supply regulator for load-cell and ADC analog power supply On-chip oscillator requiring no external component with optional external crystal On-chip power-on-reset Simple digital control and serial interface: pin-driven controlsno programming needed Selectable 10SPS or 80SPS output data rate Simultaneous 50 and 60Hz supply rejection Current consumption including on-chip analog power supply regulator: normal operation < 1.5mApower down < 1uA Operation supply voltage range: 2.6 - 5.5V Operating Temperature Range:-20 degree ~ +85 degree 50kg Load Cell This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). The sensor is a group of half-bridge strain gauge, there are 3 ways to use it : 1. Use one sensor with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements. 2.Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg 3.Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg Package Includes: 4 X Load Cell 50kg 1 X HX711 Module
