Hi All, I'm trying to get a weight measurement working with my current project and i've hit a brick wall :(
I have a pair of SEN-10245 and a ina114bp amp as in the video below:
The sequence of the wires is different on each load sensor. Black,white,red vs white,black,red -> I'm not sure if this is significant.
The circuit is black of each sensor to gnd white of each sensor to 5v red of each into V_in- and V_in+ of amp
amp_ref to gnd V+ to 5v V- to gnd v_out to arduino analogue pin
between rg and rg is 5ohms for the gain setting.
I can't get any meaningful output on the reading. Seams to sit at 140 (of 1024) in the adc reading.
Any advice to making this work?
