The temperature sensor ds18b20 is a digital temperature sensor that is commonly used for temperature monitoring in various applications. The "Waterproof Temperature Sensor Wire 1 Meter" refers to a version of the temperature sensor ds18b20 that is encapsulated in a waterproof housing and comes with a 1-meter-long cable attached to it. This design makes it suitable for measuring temperature in environments where moisture or water exposure may be a concern.

Key features of the DS18B20 Waterproof Temperature Sensor with 1-meter wire include:

Digital Output: The temp sensor ds18b20 uses the 1-Wire protocol, which allows multiple sensors to communicate with a microcontroller or other devices using just a single data line. Each sensor has a unique 64-bit address, enabling easy identification in a multi-sensor setup.

Wide Temperature Range: The DS18B20 is capable of measuring a wide temperature range, typically from -55°C to +125°C (-67°F to +257°F), making it suitable for both hot and cold temperature monitoring.

High Accuracy: The DS18B20 sensor offers high accuracy in temperature measurements with resolution options up to 12 bits, providing precise readings for various applications.

Waterproof Design: The sensor's housing is sealed to make it waterproof, allowing it to be used in outdoor or harsh environments where direct exposure to water or moisture is a concern.

One-Meter Cable: The sensor comes with a 1-meter-long cable attached, which provides flexibility in installation and allows you to place the sensor at a suitable location while keeping the microcontroller or data acquisition system at a safe distance.

Applications of temp sensor ds18b20 :

Environmental Monitoring: The waterproof design makes it suitable for monitoring temperature in outdoor environments, such as weather stations or environmental monitoring systems. Aquariums and Aquatic Systems: The sensor can be used to monitor water temperature in aquariums, fish tanks, and other aquatic systems.

Industrial Automation: It can be integrated into industrial control systems to monitor temperature in factories, warehouses, and other industrial settings.

Greenhouses and Agriculture: The sensor is commonly used in greenhouses and agricultural applications to monitor temperature levels for optimal plant growth.

HVAC Systems: Heating, Ventilation, and Air Conditioning (HVAC) systems can benefit from temp sensor ds18b20 for temperature monitoring and control. Overall, the temp sensor ds18b20 with a 1-meter wire is a versatile and reliable sensor that provides accurate temperature measurements in challenging environments where water or moisture exposure is a concern.

Waterproof, and 36 inches each - nice sensor

This is a nice little temperature sensor. It's been working well as a solar powered pool thermometer. 5 sensors, each 3 feet in length. The wire are appropriately colored (red and black, and data is yellow). So far it's been just fine in the water (a few days now) so the waterproofing seems good.

Digital temp probes beat analog any day.

I bought these to put down our geothermal wells and hot springs. You can parallel them in great quantity, for very simple wiring when using multiple sensors.Every one of these has a unique serial number that allows them all to "talk" on the same wire to the microcontroller. And there's no analog sensor extra components nonsense to deal with on long wires. I can have a bunch of these down our deep well, and the maximum temperature rating will allow them to get a true picture of temperature gradient down the WWII-era tungsten ore-processing plant hot well.I've waited a LONG time to get these via eBay- here's where to get them in a hurry.

Dallas DS18b20 Temperature Sensors

I will only buy the "Waterproof" DS18B20 sensors now. I use to buy the cheaper ones with the 3 pins that you would have to solder on your own cable, but I always had issued with the cables going bad on them. Since switching to these I no longer have any problems.TIP: Black lead goes to ground. Red lead goes to 3.3vdc and yellow is your data line.

Accurate and easy to wire

These probes are easy to wire and there's tons of options for Arduino based platforms to get readings for them. I'm using at least one of them for sous vide monitoring over mqtt with an esp8266, and the logging has been accurate and stable so far. No resistors or any other external components are needed to interface with it. They also seem to be sealed really well, so no worries about water ingress when used as a immersed temperature probe.

Good value for the money

Sensors all work and are within the DS18B20 tolerance of plus or minus .5 degrees C. I'm not sure about the waterproofing yet. Would give them 5 stars if the ends of the leads were soldered or had pins on them.

Works correctly.

I previously purchased from another seller, and all 5 sensors did not work.

Amazingly surprised!

These worked out great for my Arduino. I had no issues. I would get these again if needed.

Accurate and easy

This is an accurate and easy temperature probe for 1-Wire systems.

Excellent sensors, bang-on calibration.

These are great little sensors, and well calibrated. Mine were within 0.1C absolute, and very consistent. Easy to get running on a raspberry pi, even without a pullup resistor. I'll be buying lots of these.

Aquarium Monitoring

I have them connected up to a Arduino to monitor temperatures in an aquarium.Works great and appears to be more accurate than the aquarium thermometers you buy in the stores.
