DS18B20 Temperature Sensor Module is a digital temperature sensor, and you can easily connect it to 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 via the 1-wire protocol is established. Therefore, several sensors can be connected only through one common wire to . The output is digitally accurate to 12 bits. Therefore, the temperature can be measured with a precision of 0.0625 º C. Applications: 1. 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; 2. Bearing, cylinder, textile machinery, air conditioning, and other small space industrial equipment temperature and control; , 3. 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
