DS18B20 Water Proof Temperature Probe – Black (1m)

This is the DS18B20 Water Proof Temperature Probe Ð Black (1m) Original Chip which is based on the DS18B20 sensor. It is very handy when you need to measure something far away, or in wet conditions. Because they are digital, you donÕt get any signal degradation even over long distances.
These 1-wire digital temperature sensors are fairly precise (±0.5¡C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. When using a microcontroller put a 4.7k resistor to the sensing pin, which is required as a pull-up from the DATA to the VCC line.
At the heart of the DS18B20 probe lies the DS18B20 digital temperature sensor, renowned for its high precision and wide temperature range. This sensor employs the 1-Wire communication protocol, enabling seamless integration with microcontrollers and other devices. With its digital output, the DS18B20 delivers temperature readings directly in digital format, eliminating the need for additional analog-to-digital conversion circuitry and ensuring accuracy over long transmission distances.
The waterproof casing of the DS18B20 probe is essential for protecting the sensitive internal components from moisture and environmental contaminants. Constructed from durable materials such as stainless steel or plastic, the casing provides a robust shield against water ingress, allowing the sensor to operate reliably in wet or submerged conditions. Additionally, the probeÕs design typically includes a sealed cable entry point, further enhancing its resistance to moisture penetration
