Product description: DS18B20 digital 1-Wire temperature sensor - Joy-IT KY-001
The KY-001 is a compact temperature module equipped with the popular DS18B20 digital sensor , providing accurate and stable temperature measurement. The sensor offers 9- to 12-bit resolution and an accuracy of ±0.5°C over a range of -10°C to 85°C. Using a 1-Wire bus, multiple sensors can be connected to a single data line, and each module's unique 64-bit identifier allows for individual recognition within the system. The module can be powered by 3.3V and is suitable for both simple educational projects and more advanced temperature monitoring systems, building automation, and smart home solutions. Its small size facilitates integration with prototype devices and embedded systems.

KY-001 sensor pinouts and connections
The KY-001 module features three basic pins for quick connection to a microcontroller or single-board computer. The Signal pin is responsible for communication via the 1-Wire bus, while the +V and GND pins are used to power the module. Simple configuration makes connecting the sensor to Arduino or Raspberry Pi platforms quick and easy, even for beginners. The sensor can also operate in parasite power mode , where power is drawn directly from the data lines. This solution reduces the number of wires in the project and facilitates integration into more complex measurement systems.
