DS18B20 Chip NTC Thermistor Digital Waterproof Temperature Sensor Probe for Aquarium

Description of DS18B20 Chip NTC Temperature Sensor

DS18b20 temperature detector probe adopts the brand-new and original DS18B20 temperature sensor chip.

Each pin of chip is separated by heat shrinking tube to prevent the short circuit, and sealed inside for waterproof and damp-proof. Its direct "One line Bus" digital transmission greatly improves the anti-jamming capability of system, suitable for field temperature measurement in harsh environments.
At the same time, it is sealed with a high thermal conductivity of sealing rubber strip, to ensure the temperature sensor’s high sensitivity, with a very tiny temperature delay. Its measured temperature range is from -55℃ to +125℃, in the range of -10℃~ +85℃, its accuracy is±0.5℃.
When testing it, need to connect the signal end (yellow line) of sensor to the Digital port of microcontroller, meanwhile, need to add a pull-up resistor on the Signal end, or else the test will fail.

Features of DS18B20 Chip NTC Temperature Sensor

* 3.0V ~ 5.5V power supply
* 9 to 12 adjustable resolution
* Wide temperature range of -55 ℃ ~ +125 ℃
* No external components, a unique single-bus interface
* Red (VCC), yellow (DATA), green (GND)
* Output leads: red (VCC), white (DATA), black (GND)

* Every pin of the chip is sealed and separated by the heat shrink tube. Good for insulation and to prevent short circuit. 3 output lines, * * * * * * VCC/DATA/GND. The exterior is made of PVC plastic tube, which is safe, wear-resistant and waterproof.
* The high quality 304 stainless steel probe, is resistant to high temperature, fast heat conduction and accurate reading.
* The sensor has one unique number and the temperature acquisition device identifies the corresponding temperature sensor by number.
* The field temperature is directly transmitted in the digital way of 1-Wire bus, no need the external components and greatly improves the system's anti-interference. Suitable for the harsh environments.
