DS18B20 Temperature Sensor Probe
Overview
The **DS18B20** is a digital temperature sensor probe that provides accurate temperature readings in a variety of environments. Encased in a waterproof stainless steel tube, it is ideal for outdoor or liquid temperature monitoring.
Specifications
- Temperature Range: -55°C to +125°C
- Accuracy: ±0.5°C (from -10°C to +85°C)
- Operating Voltage: 3.0V to 5.5V
- Resolution: Configurable (9-bit to 12-bit)
- Communication: 1-Wire protocol
- Stainless Steel Tube Length: Varies (common: 30mm x 6mm)
Pinout
| Pin | Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | DQ | Data I/O (Connect to a microcontroller GPIO with a pull-up resistor) |
| 3 | VDD | Power Supply (3.3V to 5.5V) |
Working Principle
The **DS18B20** uses a 1-Wire communication protocol to transmit temperature data. It contains an internal thermometer and EEPROM for user-defined settings. The sensor measures temperature, converts it into digital format, and sends the data through the DQ pin to the connected microcontroller.
The sensor can operate in "parasite power mode," requiring only two wires (GND and DQ) if a strong pull-up is used during data transfer.
Applications
- Liquid Temperature Monitoring
- Industrial and Outdoor Temperature Measurements
- HVAC Systems
- IoT and Embedded Systems
- Weather Stations
