Dual Temperature Differential Monitor Kit with Arduino Uno + LED

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Build a monitor that measures and logs temperature difference in real time — ideal for pipe heating systems, solar panels, or insulation testing. Tape the dual DS18B20 probes to a pipe's inlet and outlet to instantly see heat loss or gain. This compact project turns thermal analysis into a hands-on experience for physics labs and engineering workshops.

What You'll Build

You'll assemble a standalone instrument that reads two DS18B20 temperature sensors simultaneously, calculates the delta between them, and displays hot/cold readings plus the difference on a crisp 0.96-inch OLED screen. The onboard DS3231 real-time clock stamps every measurement, and the microSD module saves the data as a CSV file you can open in any spreadsheet. When the differential passes a user-defined threshold, the Arduino's built-in LED flashes a warning — a feature you can extend to an external
