ESP32 Arduino DS18B20 Temperature sensor.

Here are couple of quick ways to set up temperature sensing with ESP32 using DS18B20 temperature sensors. Why DS18B20 you may ask. Well here is why:

  1. Measures Temperatures from -55°C to +125°C (-67°F to +257°F)
  2. ±0.5°C Accuracy from -10°C to +85°C
  3. Programmable Resolution from 9 Bits to 12 Bits
  4. Unique 1-Wire® Interface Requires Only One Port Pin for Communication

So its accurate sensor with nice range. Plus its it doesn’t need analog pins because it uses 1-wire digital interface.

So lets get started…
