Description

DS18B20 Water Proof Temperature Probe

The DS18B20 is a 1-wire programmable Temperature sensor from maxim integrated. 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.(find out a wide range of Sensor at solicstores.in)

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.

The sensor works with the method of 1-Wire communication. It requires only the data pin connected to the microcontroller with a pull up resistor and the other two pins are used for power as shown below.

DS18B20

The pull-up resistor is used to keep the line in high state when the bus is not in use. The temperature value measured by the sensor will be stored in a 2-byte register inside the sensor. This data can be read by the using the 1- wire method by sending in a sequence of data. There are two types of commands that are to be sent to read the values, one is a ROM command and the other is function command. The address value of each ROM memory along with the sequence is given in the datasheet below. You have to read through it to understand how to communicate with the sensor.

Pin Configuration

DS18B20

No: Pin Name Description
1 Ground Connect to the ground of the circuit
2 Vcc Powers the Sensor, can be 3.3V or 5V
3 Data This pin gives output the temperature value which can be read using 1-wire method

Features :

  • Programmable Digital Temperature Sensor
  • Each pin uses a heat-shrinkable tube to prevent short circuit, internal sealing glue.
