Analog Devices Inc./Maxim Integrated DS18B20Z Environmental and export classification status description

of DS18B20Z The DS18B20Z is a digital thermometer manufactured by Dallas Semiconductor, now part of Maxim Integrated. It is designed to measure temperatures in the range of -55°C to +125°C with a resolution of 9 to 12 bits, depending on user configuration. The device uses a 1-Wire interface, allowing multiple sensors to be connected on the same data line, simplifying the wiring for multiple temperature readings. Functions - Temperature Measurement: The DS18B20Z precisely measures temperature in Celsius. - Digital Output: It provides temperature readings in a digital format, eliminating the need for analog-to-digital conversion. - Configurable Resolution: Users can set the resolution of the temperature reading from 9 to 12 bits, allowing for a balance between accuracy and speed. - 1-Wire Interface: The device communicates over a single wire, simplifying connections between the microcontroller and multiple sensors. Applications - Industrial Temperature Monitoring: Used in automation and control systems for temperature checks. - Home Automation: Integrated into smart home systems for monitoring and controlling HVAC systems. - Medical Equipment: Employed in devices that require precise temperature measurements, such as incubators. - Environmental Monitoring: Used in weather stations and climate monitoring equipment. Alternative Parts - DS18S20: Similar to the DS18B20Z but with a lower 9-bit resolution and fewer software features. - LM35: An analog temperature sensor providing output voltage proportional to the temperature. It requires an ADC for digital readings. - MCP9808: A digital temperature sensor with an I2C interface and higher accuracy. Embedded Modules - Sensor Node Modules: The DS18B20Z is often integrated into modules and sensor nodes for quick implementation, including break-out boards for easy interfacing. - Arduino Compatible Sensors: Modules that connect directly to Arduino boards for temperature readings. - Raspberry Pi Sensor HATs: Some HATs designed for Raspberry Pi include the DS18B20Z for temperature monitoring purposes.
