【Product introduction】

• The temperature sensor DS18B20 is used, and the sealant with high thermal conductivity is encapsulated, which ensures the high sensitivity of the temperature sensor and minimal temperature delay. The temperature sensor supports the "one-wire bus" interface (1-Wire), the measurement temperature range is -55°C to +125°C, and the accuracy is ±0.5°C within the range of -10 to +85°C. The field temperature is directly transmitted in the digital mode of "one-line bus", which greatly improves the anti-interference of the system. Field temperature measurement suitable for harsh environments. DS18B20 digital temperature sensors all have a unique number, and the temperature acquisition device identifies the corresponding temperature sensor through the number. The lead length of the sensor can be customized according to user needs.
• The probe adopts a brand new imported DS18B20 temperature sensor chip. Each pin of the chip is separated by a heat shrink tube to prevent short circuit, and the internal sealant is waterproof and moisture-proof!
• High-quality stainless steel tube package, waterproof, moisture-proof and rust-proof!
