Комментарии об отличиях

TSL2561 ↔ BH1750FVI

TSL2561 (ams): dual-diode (visible + IR), 16-bit, I2C addr 0x39/0x49/0x29, lux output via empirical formula, programmable integration time (13.7ms/101ms/402ms), 2mmx2mm DFN. BH1750FVI (Rohm): single-diode (visible approx), 16-bit, I2C addr 0x23/0x5C, direct lux output (no formula), fixed integration (120ms H-res/16ms L-res), WSOF-6. Отличия: TSL2561 имеет two-channel architecture (Channel 0: visible+IR, Channel 1: IR-only) для IR compensation — даёт более точный lux при разных light sources. BH1750FVI — single channel, менее точный при fluorescent/LED light. I2C address различен (0x39 vs 0x23). Instruction set: TSL2561 требует write command + read 4 bytes (CH0 low/high + CH1 low/high), BH1750FVI — write command + read 2 bytes. Integration time: TSL2561 programmable 13.7-402ms, BH1750FVI — 120ms или 16ms. Подводный камень: разные lux calculation algorithms — требуется адаптация firmware.
