4. Jumper Wires

Block Diagram

Circuit Setup

1. Connect DS18B20 Sensor to Arduino Nano:
   • Connect the VCC pin of the DS18B20 sensor to 5V on the Arduino Nano.
   • Connect the GND pin of the DS18B20 sensor to GND (ground) on the Arduino Nano.
   • Connect the DATA pin of the DS18B20 sensor to digital pin 2 on the Arduino Nano.
   • Optionally, connect a 4.7kΩ resistor between the VCC and DATA pins of the DS18B20 sensor for parasitic power mode (if applicable).

Instructions

1. Circuit Setup:

   • Wire the waterproof DS18B20 temperature sensor to the Arduino Nano as described in the circuit setup section.

2. Code Upload:

   • Open the Arduino IDE and paste the provided code.
   • Upload the code to the Arduino Nano.

3. Testing:

   • Once the code is uploaded, open the serial monitor.
   • The serial monitor will display temperature readings in Celsius obtained from the DS18B20 sensor.
   • Observe the temperature readings and verify their accuracy based on the ambient conditions.

Applications

• Environmental Monitoring: Monitor temperature in indoor and outdoor environments for climate control and analysis.
• Temperature-Controlled Systems: Use temperature sensors in systems such as heaters, coolers, and incubators to maintain specific temperature ranges.
• HVAC Systems: Integrate temperature sensors into heating, ventilation, and air conditioning systems for efficient climate control and energy savings.

Notes

• Parasitic Power Mode: The DS18B20 sensor supports parasitic power mode, where it draws power from the data line. Ensure proper wiring and configuration if using parasitic power mode.
• Calibration: Calibrate the temperature sensor if necessary to ensure accurate readings.
• Sensor Placement: Position the sensor appropriately to measure the desired temperature accurately.
