water temperature sensor DS18B20 for arduino

This video explains step by step how to setup, wire and code the DS18B20
water temperature sensor.

This can be used as a thermometer to measure temperatures in liquids as it is waterproof.

A DS18B20 sensor is a good option when high accuracy applications require good responsiveness.

The DS18B20 sensor communicates with an Arduino via the 1-wire bus. By definition, only one data line (and ground) is required to communicate with the Arduino.

The operating temperature of the sensor ranges from -55°C to +125°C, with an accuracy of ±0.5°C in the range of -10°C to +85°C. In addition, the DS18B20 can receive power directly from the data line (“parasitic power supply”) without the need for an external power supply.

Thanks a lot! you are underrated sir, you deserve more views and likes

[TotalGAMIX]

I hope tons of people do this or something similar. Im definitely gonna make something like it if the experiment os successful. Thanks for doing this!

[medericbeckers]

Hello, thanks for the video. For accuracy purposes, would you recommend placing the resistor as close as possible to the arduino or to the sensor? Have a good day

[harleyrdr]

Surprised there aren't more views (and likes) on this vid. Nicely done Sir!

[Meeshow]

how do you then control a relay with a setpoint?
