Need accurate temperature sensing for your electronics project? This 15-pack of DS18B20 sensors is a fantastic deal. Each sensor has a waterproof stainless steel probe (6mm x 50mm) at the end of a 1-meter (about 3.3 ft) cable. They measure temps from -55°C to +125°C (-67°F to 257°F) with good accuracy (±0.5°C typical from -10°C to 85°C). Power them with 3.0V to 5.5V. The cable has three wires: red (VCC), black (GND), and yellow (DATA) – they use a 1-Wire interface, so they’re easy to hook up to microcontrollers like Arduino or Raspberry Pi. Perfect for weather stations, aquarium controllers, HVAC monitoring, fermentation, or any project where you need reliable, digital temperature readings. The waterproof probe lets you use them in liquids or humid environments. Get a bundle and have spares for future projects!
