![]() ![]() Multiple DS18B20 Waterproof Temperature SensorĦ. We toss in a 4.7k resistor, which is required as a pullup from the DATA to the VCC line when using the sensor.Ģ. The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex and requires a bunch of code to parse out the communication. They work great with any microcontroller using a single digital pin. It can give up to 12 bits of precision from the onboard digital-to-analog converter. These 1-wire digital temperature sensors are fairly precise, i.e ☐.5☌ over much of the range. The cable is jacketed in PVC.īecause it is digital, there is no any signal degradation even over long distances. The Sensor can measure the temperature between -55 to 125☌ (-67☏ to +257☏). Handy for when you need to measure something far away, or in wet conditions. This is a pre-wired and waterproofed version of the DS18B20 sensor. ![]() DS18B20 Waterproof Digital Temperature Sensor: It means it can connect several devices and read their values using just one digital pin of the Arduino. This comes with sealed package lets precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 temperature sensor is a 1-wire digital temperature sensor. But here i have shown connecting 3 DS18B20 Temperature Sensors to Arduino. We can connect maximum of 1024 sensors using I2C Protocol. Only one digital pin of Arduino is required to connect several temperature sensor. Simply we will connect Multiple DS18B20 Temperature Sensors to Arduino and display the temperature values of all the sensors in degree celsius or Fahrenheit. In this project we will learn about Interfacing Multiple DS18B20 Temperature Sensors to Arduino.
