Eiechip 5PCS Waterproof Temperature Probe Thermometer DS18B20 1M: Reliable Measurement with Heat Resistance Thermal Cable Review

Obviously at this price point they don't use the original DS18B20 chips but they are accurate and work well for my application, particularly an Arduino temperature controller for brewing.

They work great with my ESP8266. Simple single wire interface. For testing purposes, I'm temporarily monitoring the temperatures in my fridge and freezer, and so far so good.

Ready to use with my Raspberry Pi and the Raspbian w1 driver. The only problem I had was that on some of them the inner insulation was damaged where the outer jacket was cut at the factory, causing the conductors to snap after being shuffled on the bench, I had to cut the cable and reconnect it unlocked.

I don't have a calibrated source for 100% accuracy, but it's definitely good enough for my application. I measure air and water temperature for pool equipment, so I don't measure fractions of a degree. It reads within 1 degree of every other sensor I've compared to. It wasn't a big deal to get it working with your Raspberry Pi, just plug in and go (assuming you already have 1-wire enabled in the OS).

Hello, I bought 5 for my Arduino Mega (and ESP8266 NodeMCU 12-E). I didn't realize how badly I wanted a "single-wire" communication protocol until I bought these thermistors, which are individually 8-bit addressable and waterproof (protected?) submersible temperature sensors. on 3 leg lines/cords. I tested them all to see which ones matched best in terms of temperature. I put them in an ice bath, in boiling water, in my coffee mug with cream and noted the temperature in Fahrenheit and found…

Works out of the box with my Raspberry Pi and Raspbian w1 driver. The only problem I had was that some of them had the inner insulation damaged where the outer jacket was cut at the factory and this caused the conductors to break after mixing. Bench I had to cut the cable and re-terminate.

I bought them to measure ambient temperature and they work stably and well. I'm writing this review to reveal the following: The factory heat shrink tubing is for show only. It has no self-adhesive backing and therefore offers very little weather protection. But the inside of this thing is well potted in stainless steel tubing, so for many applications it shouldn't matter. For my outdoor use, I took off the factory heat shrink tubing and put mine on an adhesive backing. It makes me happy, but…

I have purchased several DS18B20 sensors over the past few years. Most of them, INCLUDING THIS, are counterfeit/counterfeit/cloned devices, not genuine Dallas/Maxim chips. You can initially tell they aren't from Maxim (formerly Dallas Semiconductor) unless the unique ID starts with '28' - the IDs from this recent purchase start with '01'. That doesn't mean they're bad at reading temperatures; You are doing well. But many of the clones don't allow you to run them in parasitic power mode and use…
