DS18B20 Chip NTC Thermistor Digital Waterproof Temperature Sensor Probe For Aquarium

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.
