This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.
We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.
Notes: Red wire connects to 3-5V, Black connects to ground and Yellow is data
- 3.0-5.5V input voltage
- -55°C to+125°C temperature range
- ±0.5°C accuracy from -10°C to +85°C
- 1 Wire interface
Dimensions: Stainless steel tube is 6mm in diameter and roughly 50mm long. Overall length (including wire) is 1 meter.
