HALJIA 5PCS DS18B20 Waterproof Temperature Sensors Transducer Digital Thermal Stainless Steel Probe 1m Compatible with DIY Arduino Raspberry Pi Etc.

The probe uses DS18B20 temperature sensor chip. Probe tube is made of stainless steel, waterproof, resistant to high temperature, moisture and rust, fast heat conduction and accurate reading. Voltage: 3.0 - 5.5V; Temperature range: -55℃ ～ +125℃ Probe Size : 6 x 50 mm; Wire length: 1 m; 9～12 bit adjustable resolution The field temperature is directly transmitted in the digital way of 1-Wire bus, no need the external components and greatly improves the system's anti-interference. Suitable for the harsh environments. Every pin of the chip is sealed and separated by the heat shrink tube. Good for insulation and to prevent short circuit. 3 output lines, red (VCC), yellow (DATA), black (GND). The exterior is made of PVC plastic tube, which is safe, wear-resistant and waterproof.
