DS18B20 Digital Waterproof Probe 1 Meter

This sensor is the waterproof version of the DS18B20 temperature sensor. Being a digital sensor, it can accurately measure temperature at long distances using its 1-meter cable without data loss or corruption. The DS18B20 communicates via a single-wire (1-wire) interface and supports 9 or configurable 12-bit resolution readings.

It is suitable for various applications such as indoor environments, equipment, machinery, and liquid tanks. Its stainless steel casing allows it to operate underwater.

Main Features:

• Operating Voltage: 3.0V - 5.5V
• Accuracy: ±0.5ºC from -10ºC to +80ºC
• Selectable resolution: 9 or 12 bits
• Single digital pin communication via 1-wire interface
• Temperature limit alert system
• Response time less than 750 ms
• Cable colors: Red - VCC, Black - GND, White - DATA
• Stainless steel casing, 6mm diameter, 30mm length
• Cable length: 1 meter
• Waterproof design

Typical Applications:

• Aquariums: Monitor water temperature
• Hot Water Systems: Temperature control
• Farms: Temperature monitoring in animal waterers
• Weather Stations: Outdoor temperature measurement

Connection and Programming:

Typically connected to a microcontroller (e.g., Arduino). A 4.7kΩ pull-up resistor is required between the data line and the power supply for proper operation.

Common Arduino libraries used for DS18B20 are OneWire and DallasTemperature to facilitate sensor reading and configuration.
