DS18b20

• The DS18B20 is a 1-wire programmable Temperature sensor.
• It is widely used to measure temperature in hard environments like in chemical solutions, mines or soil etc. The constriction of the sensor is rugged and also can be purchased with a waterproof option making the mounting process easy. It can measure a wide range of temperature from -55°C to 125° with a decent accuracy of ±5°C.
• Each sensor has a unique address and requires only one pin of the MCU to transfer data so it a very good choice for measuring temperature at multiple points without compromising much of your digital pins on the microcontroller.

Applications

• Measuring temperature at hard environments
• Liquid temperature measurement
• Applications where temperature has to be measured at multiple points
