DS18B20 TEMPERATURE SENSOR
Read temperature from a digital sensor.
Use a DS18B20 sensor module for temperature logging, displays and controller projects. The digital interface reduces the need for analog measurement circuitry.
Before you order: Match power, signal levels and the connector pinout to your host before connecting the module.
Features
- Power indicator
| Working voltage | 3.3~5.5V |
|---|---|
| Working temperature | -10℃~85℃，±0.5℃ |
| Size | 21x10mm |
Pinout & connections
| Pin | Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | DQ | Signal |
| 3 | VCC | Connect to 3.3V or 5V |
- Arduino library
References:
Getting started
- Confirm the power, ground and signal pinout.
- Connect to a suitable input or bus on your controller.
- Read a basic sample and check its response in the intended environment.
Frequently asked questions
Can I use the reading directly in my application?
Check the response with your host and the conditions where it will be used. Analog signals and threshold outputs require different processing from digital measurements.
