DS18B20 is a popular digital temperature sensor that can be easily integrated into various projects, including those requiring measurements in wet or harsh environments. The “waterproof” version of this sensor is encased in a sealed probe, making it suitable for a wide range of applications. When paired with the DFRO055 adapter, it simplifies the connection to a microcontroller.
DS18B20 Waterproof Temperature Sensor
The core of the waterproof temperature sensor is the DS18B20 chip. Unlike analog sensors, the DS18B20 communicates digitally, which means it is less susceptible to noise and signal degradation over long wire lengths. A key feature is its “1-Wire” interface, which allows a single data line to communicate with multiple sensors, simplifying wiring and reducing the number of microcontroller pins required.
Specifications
* Operating Voltage: 3.0V to 5.5V
* Temperature Range: -55°C to +125°C (-67°F to +257°F)
* Accuracy: ±0.5°C over the range of -10°C to +85°C.
* Resolution: 9 to 12 bits, configurable via software.
* Waterproof Probe: The sensor is encapsulated in a stainless steel tube, typically 6mm in diameter and 30mm or 50mm long, with a waterproof seal.
* Cable: Comes with a cable, usually 1 meter long, with three wires: red (VCC), black or yellow (GND), and white (Data).
DFRO055 Adapter for DS18B20
The DFRO055 adapter is a small, easy-to-use module designed to connect the DS18B20 waterproof sensor to a microcontroller. Its primary purpose is to provide the necessary pull-up resistor for the 1-Wire protocol and to offer a convenient screw terminal for a secure connection. This eliminates the need for breadboards or soldering a resistor, making prototyping quicker and more reliable.
Specifications
* Input: Screw terminals for connecting the DS18B20’s three wires (VCC, GND, and Data).
* Output: A 3-pin header that can be plugged directly into a breadboard or an Arduino’s digital pin.
* Pull-up Resistor: The adapter includes a built-in 4.7kΩ pull-up resistor between the data line and the VCC line, which is essential for the 1-Wire communication protocol.
* Indicator LED: Some versions may include a power indicator LED for quick visual confirmation.
