Robust and reliable
Used this in an outdoor weather station. It has survived rain and freezing temperatures without failing. The 1-wire protocol makes wiring multiple sensors very easy.

Works as advertised
Standard DS18B20 performance. Nothing fancy, but it does exactly what it says. The waterproof seal on the probe looks professional. Deducted one star because the connector wasn't included, just bare wires.

Perfect for my aquarium project
This sensor works flawlessly with my Arduino setup. The waterproofing is solid, and I've had it submerged in my tank for two weeks with no issues. Readings are consistent and match my separate thermometer.

Great for smart home integration
Integrated this into my Home Assistant dashboard. Response time is quick, and the data is stable. Highly recommend for anyone building a custom thermostat solution.

Good value, accurate readings
I bought five of these for a home brewing temperature monitoring system. They are accurate within the stated range. The only minor issue is the cable could be a bit more flexible, but overall great value.

Essential for soil monitoring
I use this to monitor soil temperature in my greenhouse. The stainless steel probe is durable and doesn't corrode. Setup was straightforward with my Raspberry Pi.
Q: What library do you recommend for using this with Arduino?
A: We recommend the standard 'OneWire' and 'DallasTemperature' libraries available in the Arduino Library Manager. They are fully compatible with the DS18B20 chip.
Q: Does this module require an external pull-up resistor?
A: Yes, the 1-Wire protocol typically requires a 4.7kΩ pull-up resistor between the data line and VCC. Some breakout boards include this, but if connecting raw wires, you will need to add one.
Q: Can this sensor be used directly in saltwater?
A: Yes, the stainless steel 304 probe is resistant to corrosion and suitable for saltwater applications like marine aquariums, though prolonged exposure should be monitored.
Q: Is the cable length customizable if I need 5 meters?
A: The standard listing comes with a 1-meter cable. However, we offer custom lengths up to 10 meters upon request via our contact form or bulk order options.
Q: What is the maximum operating voltage?
A: The DS18B20 sensor operates safely between 3.0V and 5.5V DC. Exceeding 5.5V may damage the internal circuitry.
