DS18B20 Temperature Sensor Module is a digital temperature sensor , and you can easily connect it to Arduino with only one 4.7-pound resistor, base 1 – Ground 2 – Output – Base 3 to the positive of the source, with resistance to base 2 Is connected. The connection of this sensor to the Arduino via the 1-wire protocol is established. Therefore, several sensors can be connected only through one common wire to Arduino. The output is digitally accurate to 12 bits. Therefore, the temperature can be measured with a precision of 0.0625 º C.
Applications:
DS18B20 Temperature Sensor is suitable for the cold storage, granaries, storage tanks, telecommunications room, electric power room, cable trough, and other temperature measurement and control areas; bearing, cylinder, textile machinery, air conditioning, and other small space industrial equipment temperature and control; , Refrigerator, freezer, and low-temperature drying oven, etc. heating/cooling pipe calorie measurement, central air conditioning household thermal energy measurement and industrial temperature measurement and control and Many more..
