Review on 🌡️ 10-Pack Eiechip 18B20 DS18B20 TO-92 3-Pins Wire Digital Thermometer Temperature IC Sensor by Andrew Dickens

They work exactly as they should. I was pleasantly surprised that the entire batch of 20 worked to spec. I bought two batches of "Eiechip 10Pcs 18B20 DS18B20 TO-92 3 Pin Wire Digital Thermometer Temperature IC Sensor" (20 total) because they are inexpensive enough to experiment with and the 1-wire interface makes it easy to both individually and to connect multiple modules. Maxim Integrated (formerly Dallas) specifications are +/- 0.5°C; each achieved 0.49°C or less over multiple days of testing at room temperature. I expect results may vary by device (-10°C to +85°C, ie +14°F to 185°F), but I think 0.5°C at ambient is great for my application to measure the temperature inside/outside our house. The "excluded" measurement in my result sheet photo is another brand of DS18B20 that monitors computer temperature.
