WWZMDiB DS18B20 Temperature Sensor High-Accuracy Waterproof for Arduino Raspberry Pi DIY and Other Experiments

works well with raspberry pi zero w

Works well with arduino if you know how that stuff works. Easy to read annalog signal.

Overall, this is a good product and I would purchase again. So here's the full story. I'm using 3 of these in 1 Arduino project as a replacement for my original DHT22's. Making this change required adding a 4.7K pull-up resister to the circuit board. In addition, the DS18B20 required that I change temp sensor libraries. The DS18B220 requires that you use the DallasTemperature library, but that's readily available so o no problem there either.Be aware that the resisters shipped with this product are 47K. resisters. But the DS18B20 requires a 4.7K resister. Duh, stupid me. I blindly use the resisters that shipped with it and had problems. Once I replaced them with the proper 4.7K resister, the problems went away.The Good:1) Running 3 sensors, all next to each other, are at most 0.75 of a degree F of each other. That's within the stated spec. But they usually do better that with the norm being only 0.25 of a degree variation.2) I like the ling WATER PROOD cable. Ideal for outdoor use.3) Excellent temperature range. Way better than even the DHT22.The Bad:1) They're sloooow. To read 3 temp sensors in one pass on different channels can take up to 2 seconds. DHT22's are much faster.2) You may need to modify your circuit board to add the 4.7k resister that the DHT22 does not need.3) The special device library is not compatible with the more standard DHT sensor library, so you will need to code accordingly.Overall, this sensor works good and has it's place.

The sensor is working fine

Have used a couple of them so far. Calibration was within spec and waterproofing seems durable.
