DS18B20 Pin Definition
DS18B20 Note
1. Ensure correct wiring. Do not reverse the positive and negative connections, as it could cause the electronic components on the board to be damaged.
2. The module does not require an external pull-up resistor. The module already provides a pull-up resistor. After the correct connection is made, the power indicator light will turn on. Then, after downloading the corresponding driver program, you can start using it.
DS18B20 Application
1. Portable applications, such as mobile phones and wearable devices.
2. Temperature monitoring
3. Smart home appliance system
4. Water temperature measurement
5. Temperature monitoring system for buildings, equipment or computer rooms
6. Process detection and control system
