Waterproof Temperature Sensor (DS18B20) 3m

This waterproof temperature sensor contains a DS18B20 sensor chip with a 1-wire communication. The DS18B20 is a digital temperature sensor in a TO92 housing. The sensor is very accurate and reliable since it has been factory-calibrated. For control with an Arduino, you can use the «DallasTemperature» library. To read the DS18B20, you only need an input from your Arduino. Multiple sensors can also be managed on one input. For the sensor to operate, you need a 4.7 kOhm resistor which you switch between VCC and Data. (For example, if you have 5 sensors on the same input, you only need one resistor).

If you have questions or problems with control or suggestions about the product description, just send us an email or use the review function. We're happy to help.
