## Summary description

Digital temperature sensor based on DS18B20 in CT-DS18B20/3M configuration with a 3 m cable. Uses the 1‑wire interface for temperature measurement and digital output, suitable for integration with microcontrollers and monitoring systems. Ideal for ambient, enclosure or HVAC temperature sensing where a simple, single-wire digital sensor is required.

## Long description

The Temperature sensor DS18B20 CT-DS18B20/3M is a compact digital thermometer based on the DS18B20 integrated circuit and supplied with a 3 m cable. It uses the 1-wire communication protocol to deliver calibrated temperature readings in digital form, enabling straightforward connection to microcontrollers, single-board computers and dedicated monitoring systems. The sealed probe and cable make the sensor suitable for placement inside enclosures or other indoor locations where a robust and cable-ready temperature sensor is required.
Advantages
The DS18B20 sensor provides accurate digital temperature measurement without the need for analog-to-digital conversion, reducing wiring complexity by using the 1-wire interface. The three meter cable allows flexible installation distance between the sensor probe and the host controller. The compact probe and corrosion-resistant cable jacket support use in confined spaces and typical indoor monitoring environments.
Suitable for
 Ambient room temperature monitoring
 Enclosure and cabinet temperature sensing
 HVAC system monitoring and control
 Integration with microcontroller projects and single-board computers
 Data logging and remote temperature measurement where a single-wire digital sensor is preferred
Key specifications
 Sensor type: digital temperature sensor (DS18B20 core)
 Interface: 1-wire digital communication
 Cable length: 3 m
 Probe format: compact sealed probe suitable for indoor use
 Output: calibrated digital temperature value
How to use
Wire the sensor to the host device following the 1-wire connection scheme: data line, ground and optional pull-up to the data line if using parasitic power is not intended. Connect the data line to a compatible GPIO or 1-wire bus input on the microcontroller or controller board, supply ground reference, and configure the host to poll the sensor using DS18B20 libraries or drivers. The sensor returns temperature readings in digital form that can be read periodically or on demand. Ensure the cable and probe are fixed to prevent strain on the connections.
Usage recommendations
For reliable readings, avoid placing the probe in direct sunlight or near local heat sources. If the sensor is used inside an enclosure, allow airflow or place the probe where it measures the representative internal temperature. Use a stable pull-up resistor on the data line when multiple sensors share the same bus, and consult DS18B20 driver documentation for correct timing and addressing when integrating several sensors.
