Hi, I am interested in purchasing the SEN-14727 miniature load cell to measure weight accurate to 1g with a 5V source. I need it to output 2 analogue signals which can be amplified by an ADS1115 ADC, to then be used with a Raspberry Pi to measure weight using I2C with a GPIO interrupt. I wanted to ask if this load cell is a suitable choice for this application?
Thank you for any advice you can offer.

Yes, I think so. That load cell could be used with 5 volt excitation and, assuming adequate mounting and calibration, could be expected to maintain a 1 gram tolerance; it’s 1% of capacity.
However, the load cell does not have two signals, do you mean the pair of wires?
In any case, I highly recommend buying a purpose built scale chip & board instead of trying to use a general purpose A/D like proposed. Here’s a flashy fun red one, totally found at random.
