Good sensor, cable stiff
Works well but the cable is a bit rigid for tight spaces. Otherwise performance is excellent.

Solid build quality
The stainless steel feels durable. No leaks after weeks underwater in my hydroponics system.

Easy Arduino integration
Found plenty of libraries online. Plug and play basically. Saved me a lot of time.
Q: Does this need a resistor?
A: Yes, a 4.7k pull-up resistor is recommended between data and VCC lines.
Q: Can I extend the cable?
A: Yes, but keep extensions short to avoid signal loss on the 1-Wire bus.
Q: What is the response time?
A: Typically less than 10 seconds in water depending on volume.
Q: Is it food safe?
A: The steel is 304 grade, but we do not certify for direct food contact.
Q: Works with 3.3V logic?
A: Yes, it operates between 3.0V and 5.5V comfortably.
