Electronic board based on the HX711 chip, a 24-bit analog-to-digital converter, specifically designed to interface the load cell to a microcontroller such as Arduino, Fishino or compatible. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier.
In Load cells and weight sensors the output range of a strain gauge is very small and thus the signal needs to be amplified before processing to prevent introduction of errors.
This module is used for amplifying the weight sensor and converting its analog sensor to digital one, therefore increasing the measurement accuracy. The output to your micro-controller /Ardunino is serial.
The module can be connected to 2 weight sensors at the same time. The module also provide power directly to sensors through out+ pin.
