DS18B20T TO-92 Temperature Sensors IC

The DS18B20T TO-92 Temperature Sensors IC is a digital temperature sensor integrated circuit (IC) housed in a TO-92 through-hole package. It provides 9- to 12-bit temperature measurements over a wide range and is known for its simplicity and accuracy, communicating via a unique 1-Wire interface. Features: Digital output: The sensor provides temperature data in a digital format, simplifying its integration with microcontrollers. 1-Wire interface: It requires only a single data line (plus ground) for communication, minimizing the wiring complexity. Wide temperature range: It can measure temperatures from -55°C to 125°C (-67°F to 257°F). High accuracy: The sensor offers an accuracy of ±0.5°C over the range of -10°C to 85°C. Programmable resolution: The measurement resolution can be configured from 9 to 12 bits, with the default being 12 bits. Multi-drop capability: Each sensor has a unique 64-bit serial code, allowing multiple DS18B20s to be connected to the same 1-Wire bus. Parasitic power mode: The sensor can draw power directly from the data line, eliminating the need for a separate power supply. Alarm function: The IC has nonvolatile, user-programmable upper and lower alarm trigger points. Specifications: Type:Programmable resolution single bus temperature sensor Supply Voltage(Vcc):2.5~5.5 Quiescent Current: Iq(Typ) (mA):1 Precision: ±0.4 Interface Type:monobus Operation Temperature Range (℃): -55~125 Package Type:TO-92 Pin configuration: The DS18B20 in a TO-92 package has three pins: Pin 1: Ground (GND) – Connects to the circuit’s ground. Pin 2: Data (DQ) – The 1-Wire interface pin for communication with a microcontroller. A 4.7 kΩ pull-up resistor is required for standard operation. Pin 3: Power (VCC) – The power supply input, typically 3.0V to 5.5V. Applications: The robust and versatile nature of the DS18B20 makes it suitable for a wide array of temperature-sensing applications. HVAC systems: For environmental controls and temperature monitoring inside buildings. Industrial systems: For process monitoring and controlling machinery or equipment. Consumer products: Embedded in devices like smart thermostats. Harsh environments: Specialized waterproof versions (often found as temperature probes) are used for measuring temperatures in soil, chemical solutions, or liquids. Weather stations: For ambient temperature measurement. Liquid temperature monitoring: In aquariums, swimming pools, or hot water tanks.
