1m Cable Temperature Sensor for Arduino and Raspberry Pi Projects

Temperature sensor DS18B20 waterproof cable 1m 2pcs. DS18B20 in a waterproof housing on a 1 meter cable is a digital temperature sensor operating at 3.3V and 5V. Supports multiple sensors on one cable: The sensors feature a 1-wire interface that allows communication using only one data line and enables connection of multiple sensors on the same cable. Each DS18B20 sensor has a unique serial number, allowing individual identification, which reduces wiring and conserves microcontroller ports. Connection method is shown in the product gallery. For accurate temperature readings, a 4.7 kΩ pull-up resistor is required between the VCC terminal (red) and the DATA terminal (yellow); resistor not included. Sensor supports parasitic power mode, enabling operation with only two wires; connection details are shown in the gallery. Specifications: Power supply: 3.3-5V. Temperature range: -55°C to 125°C.
