It depends on what you consider “accurate”. For home/diy usage, +/-10% may be absolutely sufficient as long as the error is stable (i.E: it always is a similar offset). For lab/industrial usage, 0.1% may be too far off. There’s a large gap in engineering effort that drives up the prices for more precise sensors.
