Circuit Diagram

Circuit Setup

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.
