Description

The DS18S20+T&R is a digital thermometer sensor produced by Maxim Integrated, widely used for temperature measurement applications. It features a 1-Wire communication interface, allowing multiple sensors to be connected in parallel using a single data line, which simplifies wiring and connectivity. The sensor provides 9-bit temperature readings with an accuracy of ±0.5°C over a range from -55°C to +125°C. The "T&R" in its name indicates "Tape and Reel" packaging, which is a convenient format for automated manufacturing processes.
The DS18S20+T&R requires a unique 64-bit serial code, allowing for easy identification when multiple sensors are connected on the same bus. Additionally, it supports "parasite power" mode, enabling the sensor to draw power directly from the data line, eliminating the need for an external power supply in some configurations. This makes it ideal for applications in HVAC systems, thermostats, and industrial temperature monitoring. With its robust design and efficient communication protocol, the DS18S20+T&R is a versatile component for precise digital temperature sensing.

Features

The DS18S20+T&R is a digital thermometer sensor from Maxim Integrated, part of the DS18S20 series, available in tape and reel packaging for automated assembly. Key features include:
1. Temperature Range: It measures temperatures from -55°C to +125°C, with an accuracy of ±0.5°C between -10°C and +85°C.
2. Output: Provides a 9-bit digital output via a 1-Wire interface, facilitating data communication and sensor control using a single data line.
3. Power Supply: Operates with a power supply range of 3.0V to 5.5V, also capable of deriving power directly from the data line ("parasite power").
4. Unique ID: Each sensor has a unique 64-bit serial code, allowing multiple sensors to be connected and identified on the same 1-Wire bus.
5. Conversion Time: Conducts temperature conversions within 750 milliseconds.
6. Simplicity: Requires minimal external components, suitable for a wide range of applications including thermostatic controls, industrial systems, and consumer electronics.
7. Package: Offered in a compact TO-92 package, making it easy to integrate into various systems.
The DS18S20+T&R is valued for its precision, simplicity, and versatility in temperature sensing applications.

Package

The DS18S20+T&R is a temperature sensor from Maxim Integrated. The "+T&R" denotes that the components are packaged in tape and reel, which is a packaging method used for automated assembly processes. This sensor typically comes in a TO-92 package, suitable for precise temperature measurements in various applications.

Pinout

The DS18S20+T&R is a digital temperature sensor from Maxim Integrated. It typically comes in a 3-pin TO-92 package. The three pins are:
1. GND (Ground): This pin is connected to the ground of the circuit.
2. DQ (Data Input/Output): This is the 1-Wire communication pin used for data transfer to and from the sensor. It requires an external pull-up resistor to function properly.
3. VDD (Power Supply): This pin supplies power to the sensor. The DS18S20 can operate in "parasite power" mode, where it derives power from the DQ line, or it can be powered directly using the VDD pin.
The DS18S20+T&R is capable of measuring temperatures from -55°C to +125°C with an accuracy of ±0.5°C over much of the range. The sensor communicates using the 1-Wire protocol, which allows multiple devices to operate on the same bus using unique addresses.

Manufacturer

The DS18S20+T&R is manufactured by Maxim Integrated, which is now part of Analog Devices, Inc. Maxim Integrated is known for designing, manufacturing, and selling analog and mixed-signal integrated circuits. The company provides semiconductor products for a wide range of industries, including consumer electronics, automotive, communications, and industrial sectors. Their product portfolio includes sensors, microcontrollers, interface solutions, and power management devices. The DS18S20+T&R is a digital thermometer sensor, commonly used in temperature measurement applications.

Application

The DS18S20+T&R is a digital temperature sensor commonly used in various applications such as environmental monitoring, HVAC systems, consumer electronics, industrial temperature control, and data logging. Its digital output and 1-Wire interface make it ideal for use in embedded systems and microcontroller-based projects where efficient temperature measurement and data communication are required. It is also used in smart thermostats, medical devices, and IoT applications for reliable and precise temperature sensing.

Equivalent

The DS18S20+T&R is a digital temperature sensor by Maxim Integrated. Equivalent products include the DS18B20, which offers similar functionality with slightly improved accuracy and features. Another alternative is the DHT22, which includes both temperature and humidity sensing capabilities but operates at a slower data rate. For 1-Wire communication compatibility, also consider devices like the AM2302. Ensure to check specific requirements like precision, range, and interface compatibility when choosing an equivalent.
