Sensor DS18B20 3m

On order

Price: 7,50 € inc. VAT

The DS18B20 sensor is a digital thermometer with calibrated accuracy of ±0.5°C and resolution of up to 12 bits. Temperature information is transmitted digitally from the sensor to the Arduino, so there is no distortion of the measured value or change due to interference. The DS18B20 uses a simple 1-Wire communication interface that requires only one wire for data transmission. The temperature range is -55 ÷ +125°C and the resolution is up to ±0.0625°C. In our application, we use it to measure the temperature of the floor in the house.

 

Features

  • Cable length of 300cm (sufficient length for connection behind a switch, for example)
  • The sensor is housed in a high-quality stainless steel case
  • Simple "1-Wire" communication interface
  • Measuring range -55 ÷ +125°C
  • Possibility to use multiple sensors on one bus
  • Fast response temperature measurement
  • A 4.7k Ohm resistor between VCC and DATA is required to connect to Arduino
