DS18B20 Temperature Sensor Module

The DS18B20 Temperature Sensor Module puts the DS18B20 digital temperature sensor on a small breakout board, ready to connect with jumper wires. The sensor sends calibrated readings over a single data wire using the 1-Wire bus, so you can read temperature with one pin on an Arduino, ESP32 or Raspberry Pi and even connect several sensors to the same pin.

DS18B20 Temperature Sensor Module Specifications

• Sensor: DS18B20 digital thermometer
• Interface: 1-Wire (one data pin)
• Measuring range: −55 °C to +125 °C
• Accuracy: ±0.5 °C from −10 °C to +85 °C
• Resolution: 9 to 12 bits, selectable (0.0625 °C at 12 bits)
• Conversion time: up to 750 ms at 12 bits
• Supply voltage: 3.0 V to 5.5 V
• Addressing: unique 64-bit serial code, so many sensors can share one bus

DS18B20 Temperature Sensor Module Applications

• Room, greenhouse and incubator temperature monitoring
• Weather stations and IoT data logging with ESP32
• Thermostats, fan control and over-temperature alarms
• Multi-point temperature measurement on one bus
• Electronics education and STEM projects

What's in the Box

• 1 × DS18B20 temperature sensor module

Tip: The data line needs a 4.7 kΩ pull-up resistor to VCC; many modules have one on the board, but add one if yours does not. In the Arduino IDE, the OneWire and DallasTemperature libraries make reading the sensor easy.
