Review on 🌡️ HiLetgo 5pcs DS18B20 Stainless Steel Waterproof Temperature Sensor Pack with 1M Probe by Kory Shelton

Using a NodeMcu and a 4.7K resistor I was able to easily test the probe. I want to use it to monitor my fridge/freezer in the garage. Because you can daisy chain multiple devices, it's easy to control different zones with one microcontroller. I used NodeMcu and Lua for test code. You need the ow 1-wire module built into the firmware. Then find ds18b20.lua on github under nodemcu-firmware lua_modules ds18b20. I used esptool to flash NodeMcu and ESplorer to flash the code. Would have given 5 stars if the ends of the wires were a bit longer and soldered. Then it would be easy to throw straight onto the breadboard. The console output looks like this: > dofile("temp_probe.lua");> Total number of DS18B20 probes: 1 Probe #1 Address: 26:FD:01:94:9F:18:03:C9Sensor 26 :FD :01: 94:9F:18:03:C9: 24.75 °C
