This wire is connected with the Nodemcu Esp8266 wifi module ground. Yellow Wire is the Data wire: we usually connect a resistor between the data wire and VCC wire, I will explain this in the circuit diagram.
The red wire is the VCC wire: the operating voltage is 3 to 5 volts. The DS18B20 Waterproof Temperature Sensor has three wires And since these sensors use the one-wire protocol you can even have multiple of them connected to the same pin and read all their temperature values independently. You can get one-wire sensors in different form factors like waterproof and high-temperature probes–these are perfect for sensing temperature in many different projects and applications. These sensors use a digital protocol to send accurate temperature readings directly to your development board without the need for an analog to digital converter or other extra hardware. One-wire temperature sensors like the DS18B20 are devices that can measure temperature with a minimal amount of hardware and wiring. I would appreciate your support in this way!Ībout the DS18B20 Waterproof Temperature Sensor: I may make a commission if you buy the components through these links.
