Visão Geral
Description
Key features of the DS18B20Z include:
- Digital Output: Provides temperature readings via a 1-Wire interface, allowing communication over a single data line.
- Wide Temperature Range: Operates from -55°C to +125°C with an accuracy of ±0.5°C within the range of -10°C to +85°C.
- Programmable Resolution: Supports 9 to 12-bit resolution, which can be adjusted to balance between precision and conversion time.
- Unique 64-bit Serial Code: Each sensor has a unique code, enabling multiple sensors to operate on the same bus.
- Power Options: Can be powered through the data line (parasitic power) or by an external power supply.
The DS18B20Z+T&R is widely used in consumer electronics, industrial systems, and environmental monitoring due to its robust features and reliable performance.

Features
The DS18B20Z+T&R provides 9-bit to 12-bit temperature readings, configurable via software, and includes an alarm function with non-volatile user-programmable upper and lower trigger points. It comes in a TO-92 package and is available on tape and reel packaging for automated assembly processes. The sensor is ideal for a wide range of applications, including industrial systems, consumer electronics, and environmental monitoring, due to its robust performance, ease of connectivity, and low power consumption.
Pinout
1. VDD (Power Supply Pin): Provides power to the sensor. The DS18B20 can operate in a range of 3.0V to 5.5V.
2. DQ (Data Pin): This is the data input/output pin used for communication with the microcontroller. It supports a 1-Wire communication protocol, meaning it requires only one data line (and ground) for communication and power (parasite power mode is also possible).
3. GND (Ground Pin): Connects to the ground of the circuit.
The DS18B20 is used for temperature sensing applications and provides temperature readings with a resolution of 9 to 12 bits Celsius. Its digital output makes it easy to interface with microcontrollers for applications like environmental monitoring and control systems. The “T&R” in the part number indicates it comes in tape and reel packaging for automated assembly.
