71 HX711 24-Bit ADC Module (0551-NE15)
This weighing module is available in 1KG, 5KG, 10KG, 20KG models. The self-contained backplane, 51 single-chip module and display can be used to make electronic scales.
Four leads, easy to use, plus 5-10V driving voltage, direct output as voltage signal due to force changes
[Weighing module size]: 12.7*12.7*80mm
[HX711AD module size]: 16*24mm
[Product Specifications]: 1KG, 5KG, 10KG, 20KG
[Fixed hole]: two 4mm holes; two 5mm holes (requires self-equipped screws)
[Fixed hole distance]: about 14.5mm
[product weight]: about 32 grams
Red line is connected to power supply +,
black line is connected to power supply -
green line is connected to output signal +,
white line is connected to output signal -
[Precautions]: One end of the sensor is fixed by the screw hole, and the other end is kept in a floating state. Gravity is applied according to the direction indicated by the label. Special attention must be paid not to directly press the white rubber part to avoid damage to the sensor.
Internal 1000 Ohm half-bridge strain gauge load cell, range is 50kg, half-bridge structure.
When measuring, the correct force is applied to the outer side of the strain E-shaped beam portion of the sensor (i.e., a strain gauge affixed to the middle, with a beam of white plastic cover arm) and the outside edges to form a shear force in the opposite direction, i.e., in the middle of strain beam bending necessary changes can occur under stress, strain beam side by another force can not have a barrier.
The sensor use the following three methods:
1, using a sensor with external resistors full bridge measurement range of a sensor range: 50kg. Higher requirements for external resistor
2, the use of only two full-bridge sensors measuring range is the range of the two sensors and: 50kgx2 = 100kg
3, the use of four full-bridge sensors measuring range is the range of four sensors and: 50kgx4 = 200kg
HX711-Loadcell sensor 24 bit ADC
