This kit transforms an Arduino Uno into an industrial-grade turbidity monitor that tracks bacterial growth over time - with and without an antibiotic. Turbidity, the cloudiness of a liquid culture, is the gold-standard proxy for microbial biomass. By continuously measuring broth clarity while varying antibiotic presence, you generate the inhibition curves that underpin drug development. The DS18B20 temperature probe adds thermal control context, while the DS3231 RTC and MicroSD module log every data point with a timestamp. An 0.96-inch OLED displays real-time NTU values on your bench.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA complete bioprocess data logger. Place the turbidity sensor in a bacterial broth, activate the system, and watch clarity evolve. The OLED shows current turbidity and temperature; the SD card stores a minute-by-minute record. Run one broth with antibiotic and one without, then overlay the curves to pinpoint when growth inhibition begins - exactly like a real fermentation scientist.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCalibrating a turbidity sensor to nephelometric standards using distilled water and formazin solutions\u003c\/li\u003e\n  \u003cli\u003eProgramming timestamped data logging with a DS3231 RTC and MicroSD module\u003c\/li\u003e\n  \u003cli\u003eAnalyzing bacterial growth curves from real-time turbidity - identifying lag, exponential, and death phases\u003c\/li\u003e\n  \u003cli\u003eDesigning a live OLED dashboard that switches between NTU, temperature, and elapsed experiment time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTurbidity Sensor\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS3231 RTC\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicroSD Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS18B20 Probe\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e4.7k?
