Take temperature readings from a distance, or underwater, using this Waterproof DS18B20 Digital Temperature Sensor. It's got a 90cm (0.9m) cable with a stainless steel, PVC coated probe at the end. You'll be able to use it with any 3V-5V system, and take temperature readings with an accuracy of 9-12 Bits (configurable in code). The best part is that it's digital, meaning you won't suffer any signal degradation over the longer distance. Waterproof - Take the temperatures of liquids/moist environments with the stainless steel probe. It's shrouded in PVC plastic too, meaning it will hold it's own in temperatures up to 100 degrees Celsius. Temperature - Usable from -55 degrees Celsius to 125 degrees Celsius. Accuracy of 0.5 degrees. Digital - The digital interface used to relay the readings guarantees minimal signal degradation over the longer distances (90cm for this standard cable) 1-wire interface - You can have multiple DS18B20s connected to the same central micro-controller pin as each device has a unique identifier hard-coded in. Long range - 1.5 meters of cable by default, but you can make it longer if needed Maker friendly - The DS18B20 chip is able to be powered with 3v - 5.5v which is perfect for maker platforms . HOOK-UP GUIDE This sensor is simple, you've got 3 wires (Power, Ground and Data). You simply need to connect the data pin to an input pin on your micro-controller and the power and ground to power and ground You'll also need to connect a resistor between power and signal wires, as shown in the circuit diagram on the Sensor's wiki page. Specifications TECHNICAL SPECIFICATIONS Compatible with 3.0V to 5.5V systems (development board etc) Within 0.5 degrees Celsius accuracy Recommended usable temperature range: -55 to 125 degrees Celsius Select-able 9-12 bit resolution (Factory Default at 12-bit) 1 Wire Interface Unique 64 bit ID for each sensor Query time is less than 750ms Stainless steel tube 6mm diameter by 35mm long Cable diameter: 4mm Cable Length: 90cm 100cm 200cm or Customized Technology character
