Reliable for server room monitoring
Deployed five of these across our server racks. They have been running 24/7 without any dropouts. The 1-wire protocol makes wiring multiple sensors very simple.

Great sensor, cable could be softer
Works flawlessly with my ESP32 project. The only minor downside is that the cable is a bit stiff, making it slightly hard to route in tight spaces, but the durability makes up for it.

Robust build quality
I bought the 3-meter version to reach my outdoor compost bin. The construction feels very solid, and the connection at the probe head looks like it will last for years.

Good value for money
For the price, you can't beat the accuracy. It's not industrial grade laboratory equipment, but for hobbyist and general monitoring purposes, it is spot on.

Accurate brewing temperatures
Using this to monitor fermentation temps. It responds quickly to changes and the stainless steel probe is easy to sanitize. Highly recommended for home brewers.

Perfect for my hydroponic setup
The waterproof seal is excellent. I've had this submerged in my nutrient tank for three months with zero issues. The readings are consistent with my calibrated lab thermometer.
Q: Can I cut the cable to make it shorter if I don't need the full length?
A: Yes, you can cut the cable to your desired length. However, you must ensure you properly strip, twist, and re-seal the wires with heat shrink tubing and waterproof glue to maintain the IP68 rating.
Q: What is the response time for temperature changes?
A: Under typical conditions in water, the probe reaches 63% of a step change in about 10 to 15 seconds. Full stabilization usually occurs within 30 to 60 seconds depending on the medium.
Q: Does this come with a pull-up resistor built into the module?
A: This specific waterproof probe version typically does not include a built-in pull-up resistor on the cable end. You will need to add a 4.7kΩ resistor between the data and VCC lines on your microcontroller board.
Q: Do you offer a bulk discount for ordering 50 units?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team via the 'Contact Seller' button on our store page with your required quantity for a custom quote.
Q: Is this compatible with Raspberry Pi GPIO pins directly?
A: Yes, the DS18B20 operates at 3.3V logic levels which are compatible with Raspberry Pi GPIO. Just remember to connect an external 4.7kΩ pull-up resistor as mentioned in our documentation.
