This kit places an Arduino Mega at the heart of a 4-relay command centre that reads two waterproof DS18B20 probes, an industrial-grade pH module, light intensity, and a real-time clock, displaying everything on an OLED panel. You'll build a system that can hold water at 57�C for 90 minutes as easily as it can feed nutrients when pH drifts out of range.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA PID-regulated immersion circulator capable of keeping a water bath within �0.5�C, alongside a fully configurable 4-channel relay board. The relays can fire a fish tank heater, a grow-bed pump, a pH-dosing peristaltic pump, and LED grow lights-all triggered by temperature thresholds, pH setpoints, or RTC events. The OLED shows live readings, active outputs, and a simple menu for adjusting targets without reconnecting to a PC.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterfacing multiple DS18B20 sensors on OneWire and calibrating the analog pH module for stable millivolt-to-pH conversion\u003c\/li\u003e\n  \u003cli\u003eImplementing a PID control loop to drive a heater via relay, avoiding overshoot and hunting\u003c\/li\u003e\n  \u003cli\u003eProgramming DS3231 RTC schedules and conditional relay logic for pumps, lighting, and dosing in a 24-hour cycle\u003c\/li\u003e\n  \u003cli\u003eBuilding a multi-page OLED interface that displays temperature, pH, light levels, and system status, with push-button menu control\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 Mega 2560\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS18B20 Waterproof\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAnalog pH Module\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\u003e4-ch Relay Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n  \u003cp\u003eCooking - Controls fish tank heater, grow bed pump, pH dosing, grow light via relays based on pH, temp and RTC schedule.\u003c\/p\u003e\n  \u003ch4\u003eWhat's in this kit\u003c\/h4\u003e\n  \u003cul\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/mega-2560-r3-development-board-arduino-compatible-54-io-256kb\"\u003eArduino Mega 2560\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/ds18b20-waterproof-temperature-sensor-probe-55c-to-125c\"\u003eDS18B20 Waterproof\u003c\/a\u003e x2\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/liquid-ph-0-14-sensor-module-with-bnc-probe-for-arduino\"\u003eAnalog pH Module\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/ds3231-real-time-clock-module-i2c-rtc-with-battery-backup\"\u003eDS3231 RTC\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/4-channel-relay-opto-isolated-input-board-compoden\"\u003e4-ch Relay Module\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/gy-30-bh1750fvi-light-intensity-sensor-module-for-arduinoesp\"\u003eBH1750\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"\/products\/096in-oled-display-128x64-i2cspi-for-arduino-raspberry-pi\"\u003e0.96in OLED\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/diode-variety-pack-1n4007-1n4148-1n5819-zener-assortment\"\u003e1N4007 Diode\u003c\/a\u003e x10\u003c\/li\u003e\n    \u003cli\u003e\n\u003ca href=\"\/products\/resistor-variety-pack-100-pcs-10-values-14w-carbon-film\"\u003e4.7k?
