DS18B20 – Waterproof Temperature Sensor
Dimensions: DS18B20 Temperature Sensor Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.
Description : DS18B20 Temperature Sensor
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 sensor 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.

- Simple Sketch Code
- mbed Example
- 3.0-5.5V input voltage
- -55°C to+125°C temperature range
- ±0.5°C accuracy from -10°C to +85°C
- 1 Wire interface
Unique 1-Wire® Interface Requires Only One Port Pin for Communication as a result best accuracy.
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.
- 1Hence in the Overall aspects this sensor is more accurate and durable and waterproof,1Unique 1-Wire<sup>®</sup> Interface Requires Only One Port Pin for Communication as a result best accuracy..1<span style="color: #000000;"><strong>More Products:</strong></span>1<a href="https://www.roboelements.com/product/hc05-bluetooth-module/">HC05 Bluetooth Module</a>1<a href="https://www.roboelements.com/product/lm35-temperature-sensor/">LM35 Temperature Sensor</a>1<a href="https://www.roboelements.com/product/dht111-temperature-humidity-sensor/">DHT111 Temperature Humidity Sensor</a>
