Ds18b20 temperature sensor wiring harness
DS18B20 sensor wiring harness is a commonly used digital temperature sensor. The output is a digital signal, which has the characteristics of small size, basso sovraccarico hardware, forte capacità anti-interferenza, and high accuracy. DS18B20 digital temperature sensor is easy to connect, and it can be applied to many occasions after being packaged, such as pipe type, screw type, magnet type, and stainless steel package type. There are various models, incluso LTM8877, LTM8874 and so on.
This paper proposes an automatic identification method for multiple digital temperature sensors DS18B20 on a single bus. By designing a circuit composed of a decoder 74LS138, a two-input four-NAND gate 74LS00P, and an analog switch CD4066, the DS18B20 digital temperature sensor software program is written using the Keil C51 tool. Under the control of the microcontroller, the system obtains and saves the serial numbers of all sensors in the form of power-on initialization, automatically identifies the sensors, and performs multi-point temperature measurement. The experimental results show that the system can match the obtained serial numbers with each sensor, so that the sensors can be installed and used, realizing true automatic identification.

Ds18b20 temperature sensor and 3.5mm audio connector
1, Technical performance description:
①, a unique single-wire interface,DS18B20 in the connection with the microprocessor only need a port line to achieve the two-way communication with the microprocessor DS18B20.
②, intervallo di temperatura -55 ℃ ~ +125 ℃, the inherent temperature error (note, not the resolution,Here before is wrong) 1 ℃.
③, support multi-point networking,Multiple DS18B20 can be connected in parallel on a single three-wire,Can only be 8 in parallel,To achieve multi-point temperature measurement,If the number is too large,Will make the power supply voltage is too low,Thus causing the signal transmission instability.
④, Alimentazione elettrica: 3.0 ~ 5.5V / DC (parasitic power supply can be data lines)
⑤, in use does not require any external components
⑥, the measurement results in 9 to 12-bit digital serial transmission mode
⑦, stainless steel tube diameter Φ6
⑧, for DN15 ~ 25, DN40 ~ DN250 various media industrial pipe and small space equipment temperature measurement
⑨, the standard installation thread M10X1, M12X1.5, G1 / 2 “opzionale
⑩, PVC cable direct outlet or German ball junction box outlet,Easy to connect with other electrical equipment.
