DS18B20 Waterproof Temperature Sensor Probe

The digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and almost has an alarm function with nonvolatile. user-programmable upper and lower trigger points.  the sensor communicates over a 1-Wire bus that by definition requires only .one data line (and ground) for communication with a central microprocessor. Hence, In addition, the sensor can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.

Each Sensor has a unique 64-bit serial code which results which allows multiple sensors to function on the same 1-Wire bus. so, it is simple to use one microprocessor .to control many distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, so temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.

    DS18B20 Waterproof Temperature Sensor TECHNICAL DETAILS

    Not for use in salt water or other corrosive environments.Cable specs:

    • Stainless steel tube 6mm diameter by 30mm long
    • Cable is 36″ long / 91cm, 4mm diameter
    • Contains DS18B20 temperature sensor
    • If your sensor has four wires – Red connects to 3-5V hence  Black connects to ground and White is data. The copper wire is soldered to the wire shielding
    • If your sensor has three wires – Red connects to 3-5V, Blue/Black connects to ground hence Yellow/White is data.
