概述
Description
The sensor provides temperature readings with a resolution ranging from 9 to 12 bits, allowing for adjustments based on the required accuracy and data acquisition speed. It operates within a temperature range of -55°C to +125°C with an accuracy of ±0.5°C in the -10°C to +85°C range. The DS18B20Z+ can be powered through its data line (parasite power) or externally, providing flexibility in various deployment scenarios. Its small package and low power consumption make it ideal for use in portable and space-constrained applications. The sensor is also known for its robustness and reliability in different environmental conditions.
Equivalent
1. DS18B20 - The standard model without the "+" designation.
2. DS18S20 - Similar digital temperature sensor with slightly different resolution.
3. DHT22 (AM2302) - A digital temperature and humidity sensor.
4. TMP36 - An analog temperature sensor.
5. LM35 - Another analog temperature sensor.
Keep in mind that while these alternatives may offer similar functionalities, their interfaces and specifications might differ.
Features
1. Temperature Range: It measures temperatures from -55°C to +125°C with an accuracy of ±0.5°C over a range of -10°C to +85°C.
2. Resolution: Offers user-selectable resolution from 9 to 12 bits.
3. One-Wire Interface: Utilizes a unique 1-Wire interface that requires only one data line (and ground) for communication.
4. Unique 64-Bit Serial Code: Each sensor has a unique 64-bit serial code, allowing multiple sensors to be connected to the same bus.
5. No External Components: Does not require any external components, facilitating easy setup and deployment.
6. Power Supply Options: Can be powered either through an external power supply or parasitically via the data line.
7. Alert Feature: Includes a programmable temperature alarm function with nonvolatile user-programmable upper and lower trigger points.
8. Applications: Suitable for applications including thermostatic controls, industrial systems, consumer products, and thermometers.
The compact 3-pin TO-92 package or 8-pin SOIC package options make it adaptable for various applications requiring precise temperature monitoring.
Pinout
1. GND (Ground): This pin is used to connect the sensor to the ground of the system it is interfacing with.
2. DQ (Data): This pin serves as a data line for communication. It is used to send and receive data to and from a microcontroller. The DS18B20 operates on a 1-Wire protocol, allowing for data transmission over a single data line.
3. VDD (Power Supply): This pin can be used to power the sensor with a supply voltage, typically between 3.0V and 5.5V. However, the DS18B20 can also operate in "parasite power" mode, which uses the DQ line for power, eliminating the need for a direct connection to a power supply on the VDD pin.
The DS18B20Z+ measures temperature with a high degree of accuracy and provides a digital output. It is widely used in various applications due to its simplicity, low cost, and ease of integration with microcontrollers.
