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).


  • 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


where can i get the codings?
( sanji, 25/03/2020 )
Hi, you may refer to this link. Thanks :)
can I use this in GrovePi?
( Pagupathi A/P Devandran Pillai , 29/02/2020 )
Hi, we're sorry as it is not suitable. Thanks :)
I don't see the DS18B20 sensor. Is this a wire probe with a built-in DS18B20 sensor or have to buy the DS18B20 sensor separately? ( Lim Shan Kuo , 20/02/2020 )
Hi, it is a built-in sensor. Thanks :)
Can this probe be used for long term analysis? Can it measure the temperature of a liquid for long term as in for many months? ( ZJ, 07/08/2019 )
Hi, sorry we haven't tried it for a long time measured in the liquid.
Hi, may I know when will get back the stock? ( Tan, 23/07/2019 )
Hi, this item will available in 2-3weeks
Does this temperature sensor conductive? because I want to measure temperature of a liquid of an ohmic heater. This ohmic heater uses Alternate Current to Heat the liquid. ( Mark, 03/04/2018 )
Hi, the waterproof sealed with stainless steel, it is poor conductor compare to copper. We're not sure it is applicable on your application or not, you need to try. Thanks.
Hi, good morning. what is the current spect for this temperature sensor.? ( aiman , 17/08/2017 )
Hi, you may refer to the product page and look at the attachment tab. We do have all information there. :)
Hi, may I know if I can use this sensor to measure body temperature? ( yj, 30/05/2017 )
Hi, this sensor is designed for measuring liquid temperature. You can use for measuring body temperature, however we are not sure the effect on the reading. Thanks.
Is the 3 wires isolated from the temperature probe? If liquid has high AC and DC voltage, will this product still work? ( andy, 03/11/2016 )
Not answered yet.
Can this sensor be use with PR22 board? ( Wahidatul, 17/10/2016 )


No, you cannot use it. It does not contain output pin for temparature sensor.

If you have further question, you can ask at our technical forum, as this session is only for short inquiry. Thanks. :)
