Description
The Keyestudio DS18B20 Digital Temperature Sensor is a waterproof kit that includes 3 sensors and a 4.7k resistor for use with Arduino boards. It is designed to measure the temperature of air and liquids like water. The sensor has a unique 1-Wire interface, integrated temperature sensor and EEPROM, and can measure temperatures from -55C to +125C with an accuracy of 0.5C. It also has programmable resolution and can operate in parasitic power mode with only 2 pins. The sensor is useful for applications such as thermostatic controls, industrial systems, consumer products, thermometers, and thermally sensitive systems. To use the sensor, an Arduino board, 4.7k resistor, and breadboard are also needed.
