About DIYmalls 4pcs Load Cell 50kg Half Bridge Strain
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
