Product review & video
today I'm going to show you how to set up the D s 18 B 20 water proof temperature sensor coming up next I need to measure and monitor water temperatures for an aquaponics project and this is perfect for this application I've included a link in the video description to the datasheet so you can read that if you want to get more of the technical specifications okay let's go the supplies I'm using today include a four point seven five kilo ohm resistor the sensor of course breadboard jumper cables and the Raspberry Pi as you can see there's only three wires on this thing red is four volts 3.3 volts black is ground and yellow is the data wire so I'm going to put these three wires into the breadboard and then make the connections I'm plugging in the red wire which is 3.3 volts into the Raspberry Pi and then there's the yellow data wire and I'm going to plug this into the GPIO for then I'm goi
