DS18B20 Temperature Sensor Wire is a digital temperature sensor with a waterproof stainless steel probe, designed for accurate and reliable temperature measurement in a wide range of applications. Unlike analog sensors, the DS18B20 provides direct digital output using the 1-Wire communication protocol, allowing multiple sensors to be connected to a single microcontroller pin.
The sensor features a wide operating temperature range from -55°C to +125°C with an accuracy of ±0.5°C in most ranges, making it suitable for precision monitoring. The waterproof casing and durable wire design make it ideal for harsh environments such as outdoor weather stations, aquariums, soil monitoring, and industrial systems.
It operates with a power supply of 3.0V to 5.5V, making it compatible with popular microcontrollers like Arduino, ESP32, Raspberry Pi, and other development boards. The DS18B20 supports both normal and parasite power modes, ensuring flexible integration.
This sensor is highly favored by hobbyists, students, and engineers for projects that require reliable and easy-to-interface temperature measurement solutions.
