Wanted to measure temperature of liquid? We are now carrying water proof temperature sensor. 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.

Dimensions: Probe is 6mm in diameter and roughly 30mm long. Overall length (including wire) is 100cm (1 meter).

Features:

• 3.0-5.5V input voltage
• Waterproof sealed with stainless steel
• -55°C to+125°C temperature range
• ±0.5°C accuracy from -10°C to +85°C
• 1 Wire interface
• Red = Vcc, White = Data, Black = GND
• Red = Vcc, Yellow = Data, Green = GND
