Simple Digital Temperature Sensing with Just One Data Line

The DS18B20 is a popular digital temperature sensor designed for applications where reliable temperature measurement and simple wiring are important.

Unlike an analog temperature sensor that requires the microcontroller to interpret an analog voltage, the DS18B20 performs temperature conversion internally and communicates the resulting digital data using the 1-Wire protocol.

This means the sensor can be connected to a compatible microcontroller using a simple three-wire arrangement:

VCC | GND | DATA

One of the biggest advantages of the DS18B20 is its ability to support multiple sensors on the same 1-Wire bus. Each DS18B20 device has a unique 64-bit identification code, allowing compatible software to distinguish between individual sensors.

This makes the sensor particularly useful for projects that need temperature measurements from multiple locations—for example, monitoring different areas of a greenhouse, water tank, equipment enclosure, or classroom experiment.

The DS18B20 supports a wide temperature range of -55°C to +125°C, with a typical accuracy specification of ±0.5°C over the -10°C to +85°C range when using a genuine DS18B20 device under appropriate operating conditions.

Its digital interface and compact form factor make it an excellent choice for IoT monitoring, environmental sensing, robotics, automation, weather stations, and STEM education.

Technical Specifications	Specification Details Sensor Type Digital Temperature Sensor Sensor IC DS18B20 Communication Protocol 1-Wire Temperature Range -55°C to +125°C Typical Accuracy ±0.5°C from -10°C to +85°C Resolution Programmable: 9-bit to 12-bit Supply Voltage 3.0V to 5.5V DC Typical Connection VCC, GND, DATA Device Identification Unique 64-bit ROM code Output Digital temperature data Application IoT, environmental monitoring, automation, robotics and STEM projects
Key Features	1-Wire Digital Communication The DS18B20 communicates digitally using the 1-Wire protocol, allowing temperature data to be transferred using a single data line. Multiple Sensors on One Bus Multiple DS18B20 sensors can share the same 1-Wire data bus. Their unique 64-bit identification codes allow compatible software to identify individual sensors. This is useful for multi-point temperature-monitoring projects. Programmable Resolution Temperature resolution can be configured from 9-bit to 12-bit, allowing developers to balance measurement resolution and conversion time according to the application. Wide Temperature Range The sensor supports measurements across a broad range of -55°C to +125°C, making it suitable for many educational and environmental monitoring applications. Digital Output Because temperature conversion occurs inside the sensor, the microcontroller receives digital data rather than needing to interpret a raw analog voltage.
How the DS18B20 Works	1. Temperature Detection The sensor measures the temperature of its surrounding environment. 2. Internal Conversion The DS18B20 converts the measured temperature into a digital value. 3. 1-Wire Communication The sensor communicates the temperature data to the microcontroller through the 1-Wire bus. 4. Software Processing The microcontroller can then display, record, transmit, or act on the temperature reading. For example, a controller could activate a fan when a predefined temperature threshold is reached or record temperature changes over time.
Multi-Sensor Temperature Monitoring	One of the most useful features of the DS18B20 is its unique device identification. Each sensor has a unique 64-bit ROM code, allowing multiple sensors to operate on a shared 1-Wire bus. A project could therefore use separate sensors for: Ambient temperature Greenhouse temperature Water temperature Electronics enclosure temperature Soil/environment experiments The actual number of sensors that can be reliably used on one bus depends on factors such as cable length, wiring topology, pull-up resistance, power arrangement, bus capacitance, and software implementation.
Arduino & ESP32 Compatibility	The DS18B20 is commonly used with: Arduino UNO Arduino Nano Arduino Mega ESP32 ESP8266 / NodeMCU Other compatible microcontroller platforms Popular Arduino libraries such as OneWire and DallasTemperature are commonly used to communicate with DS18B20 sensors. The exact wiring and software configuration depend on the specific module and microcontroller being used.
Pull-Up Resistor	The DS18B20 1-Wire bus requires an appropriate pull-up resistor on the data line for normal operation. Some DS18B20 breakout modules include the required resistor on the PCB, while other versions may not. Please verify the supplied module before assuming that an external pull-up resistor is unnecessary. For a typical standard 1-Wire configuration, a 4.7 kΩ pull-up resistor is commonly used, although the appropriate value can vary depending on the bus design and wiring conditions.
Example Applications	IoT Weather Station Measure ambient temperature and combine the data with humidity, pressure, or other environmental sensors. Smart Greenhouse Monitor temperature at multiple locations and use the readings to control fans, ventilation, or other automation systems. Water Temperature Monitoring Use an appropriately protected sensor arrangement to monitor temperature in water-based experiments or systems. Multi-Point Data Logger Place multiple DS18B20 sensors at different locations and record temperature changes over time. Equipment Monitoring Monitor the temperature of electronics enclosures, experimental equipment, or other non-critical systems. Robotics Use temperature readings as part of an environmental monitoring or automation project.
Educational Applications	The DS18B20 is useful for teaching: Digital temperature sensing 1-Wire communication Digital data acquisition Sensor networking Microcontroller programming Multi-sensor systems Data logging Environmental monitoring IoT automation Signal and communication protocols
Product Highlights	Simple 1-Wire Interface Communicate with the sensor using a single data line plus power and ground. Wide Temperature Range Supports measurements from -55°C to +125°C. Programmable Resolution Configure the sensor for 9-bit to 12-bit resolution. Multiple Sensors on One Bus Use the unique 64-bit device ID to distinguish multiple DS18B20 sensors sharing the same data line. Digital Temperature Data No analog voltage conversion is required at the microcontroller input. Excellent for STEM & IoT Ideal for Arduino, ESP32, environmental monitoring, automation, robotics, and data-logging projects.
Important Accuracy Information	The commonly specified ±0.5°C accuracy applies to the DS18B20 over the -10°C to +85°C temperature range under the manufacturer's specified conditions. Actual results in a project can vary depending on: Sensor quality Genuine vs. non-genuine device Supply conditions Installation Thermal coupling Environmental conditions Wiring Sensor placement Software implementation The sensor should not be treated as a laboratory-grade reference thermometer without appropriate calibration and validation.
