Perfect for my hydroponics setup
Works flawlessly with my ESP32. Waterproofing holds up well in water reservoirs. Accurate readings compared to my glass thermometer.

Solid build quality
The stainless steel probe feels durable. Sealing at the cable entry point looks robust. Using it for outdoor weather station.

Reliable DS18B20
Genuine sensor chip. Easy to wire up using the OneWire library. No issues with noise over the 1-meter cable.

Good sensor, wish cable was longer
Accuracy is spot on for brewing temperatures. The 1-meter cable is a bit short for my kettle setup, but I extended it easily.
Q: Can I use this with 3.3V logic boards?
A: Yes, the sensor operates between 3.0V and 5.5V, making it compatible with 3.3V systems like ESP8266.
Q: Does this require a pull-up resistor?
A: Yes, a 4.7k ohm pull-up resistor between VCC and Data line is recommended for stable communication.
Q: Is the entire cable waterproof?
A: The probe head is IP68 rated. The cable itself is water-resistant, but the USB or connector end should not be submerged.
Q: What library should I use for Arduino?
A: We recommend the DallasTemperature library along with the OneWire library for easy integration.
Q: Can I connect multiple sensors on one pin?
A: Yes, the 1-Wire protocol allows multiple sensors on the same data line, each with a unique address.
