This 24-bit analog to digital and signal conditioning module is designed specifically for weight scales, weight sensor and industrial control applications to interface directly with a bridge sensor. The module is based on HX711 chip.
In most 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
- Operating voltage range: 4.7 ~ 5.5V
- Operating temperature range: -20 ~ +85
- Can b used for 2 weight sensors at same time
- Fast and accurate 24-bit ADC
- Come with Faraday cage for noise reduction
On the weight sensor side
out+ : sensor power (connect to red wire of weight sensor
A- : Signal -ve (connect to white wire of first weight sensor)
A+ : Signal +ve (connect to green wire of first weight sensor)
GND : Weight sensor ground (connect to black wire of weight sensor)
B+ : Signal +ve (connect to green wire of second sensor)
B- : Signal -ve (connect to white wire of second sensor)
On the micro controller (arduino) side:
VCC: 5 VDC
DO : Digital Output
CK : Clock
