Description
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 |
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.
