One of the key features of the DS18B20U+T&R is its alarm function, which allows users to set upper and lower trigger points for temperature alerts. This feature is especially useful in situations where temperature control is critical and can help prevent damage or loss due to extreme temperature fluctuations

DS18B20U+T&R

Description

The DS18B20U+T&R is a digital temperature sensor from Analog Devices (Maxim Integrated). It operates on the 1-Wire interface, requiring only one pin for communication. Key features include built-in temperature measurement (-55°C to +125°C), programmable resolution (9-12 bits), and NV alarm settings. The DS18B20U+T&R is suitable for various applications, including consumer products, industrial systems, and thermally sensitive equipment.

Features

The DS18B20U+T&R is a digital temperature sensor with unique features:
1-Wire interface, requiring only one port pin for communication.
Integrated temperature sensor and EEPROM, reducing component count.
Measures temperatures from -55°C to +125°C, accurate ±0.5°C in certain ranges.
Programmable resolution from 9 to 12 bits.
Low power modes, requiring only 2 pins (DQ and GND) for operation.
Multidrop capability simplifies distributed temperature sensing applications.
Nonvolatile alarm settings are user-definable and can identify devices with temperatures outside programmed limits. The DS18B20U+T&R is suitable for various applications, including consumer products, industrial systems, thermally sensitive systems, and thermometry-related devices.

Package

The DS18B20U+T&R temperature sensor comes in various packages, including 8-pin SO (150 mils), 8-pin µSOP, and 3-pin TO-92.

Pinout

The DS18B20U+T&R temperature sensor has a pin count of 3 or 8, depending on the package: TO-92 (3-pin) or SOIC (8-pin). Functionally, it includes:
Power (VCC): Supply input for power consumption.
Data (DATA): Used for communication between the sensor and a microcontroller.
GND (Ground): Connects to the system ground. In 1-Wire interface mode, only the DATA pin is used, while VCC and GND are needed for parasitic power mode operation.

Manufacturer

The DS18B20U+T&R temperature sensor is manufactured by a joint venture between Analog Devices Inc. and Maxim Integrated, which are both leading semiconductor companies specializing in integrated circuits and technologies for various industries.

Applications

The DS18B20U+T&R temperature sensor finds applications in various sectors, including consumer products (thermometers), industrial systems (process monitoring), and thermally sensitive devices (controls). Its multidrop capability simplifies large-scale installations.

Equivalent
