SPECIFICATIONS

DS18B20 DIGITAL TEMPERATURE SENSOR

This is a waterproofed version of the DS18B20 Arduino Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125℃ the cable is jacketed in PVC so we suggest keeping it under 100℃. Because they are digital, you don’t get any signal degradation even over long distances! The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface so that only one wire (and ground) needs to be connected from a central microprocessor. Usable with 3.0-5.5V systems.

Usable with 3.0V to 5.5V power/data
±0.5℃ Accuracy from -10℃ to +85℃
Usable temperature range: -55 to 125℃ (-67℉ to +257℉)
9 to 12-bit selectable resolution
Uses 1-Wire interface- requires only one digital pin for communication
Unique 64 bit ID burned into the chip
Multiple sensors can share one pin
Temperature-limit alarm system
Query time is less than 750ms
3 wires interface:

Red wire – VCC

Black wire – GND

Yellow wire – DATA

WORKING

This project gives me the info I need about the water level in a water tank. When the level is low, the green LED is ON. When the level is medium, the yellow LED is ON. When the level is HIGH the red LED blinks at the same time with the buzzer sound. The distance from the sensor to water level is measured by the ultrasonic sensor and is printed to the LCD together with the temperature in that tank.The temperature is measured by the DS18B20 sensor
