Jaycar DS18B20 Digital Temperature Sensor – Arduino Compatible

You've got a project – a greenhouse controller, a fermentation rig, a classroom science demo – and you need a temperature reading that's actually accurate without bolting on a whole ADC board. The DS18B20 module gives you up to 12-bit resolution and 0.5° accuracy through a single digital IO pin. No external components. No analog fuss. You can daisy-chain multiple sensors on the same pin, which keeps your wiring clean when you're monitoring more than one spot. Conversion takes under a second, and the OneWire Arduino library means you're reading data in minutes, not hours of datasheet spelunking. Add to cart and get that project moving

• Up to 12-bit resolution with 0.5° accuracy
• Single digital IO pin connection – no external components needed
• Multiple sensors can share the same pin via OneWire protocol
• Conversion time under 1 second for responsive readings
• Arduino library (OneWire) available for quick integration
• Programmable resolution to match your project's precision needs
