The product is made of DALLAS company's DS18B20 networkable digital temperature sensor chip package, with wear-resistant touch, small size, easy to use, packaging in various forms, suitable for a variety of small space equipment, digital temperature measurement and control.
- Unique single-line interface, DS18B20 in connection with the microprocessor only need a mouth line to achieve the microprocessor and DS18B20 two-way communication;
- Temperature range: -55 ° ~ +125 °, the inherent temperature resolution of 0.5 °;
- Support multi-point network function, multiple DS18B20 can be connected in parallel on the only three lines, up to ---- Only 8 in parallel, if the number is too much, will make the power supply voltage is too low, resulting in signal transmission instability.
- Working power: 3 ~ 5V / DC;
- in use without any external components;
- Measurement results to 9 to 12 digital serial transmission;
- PVC cable direct outlet or German ball junction box outlet, easy and other Electrical equipment connection.
The products are 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.
