It?s<br>something you may consider using especially in applications requiring<br>several temperature sensors located at close proximity. For example, using<br>two one in and out out of a freezer. These devices are easy to use because<br>of available libraries for the more common microcontrollers such as the<br>Arduino & Raspberry Pi.<br><br><br>The DS18B20 and other 1-wire devices can also be interfaced to PCs using a<br>USB to RS232 and a 1-wire MICROLAN Windows driver.<br><br><br>They are available as discrete devices (3-PIN TO-92 package) or pre-wired<br>in waterproof leads ? all inexpensive and great specs. They are available<br>quickly from <a href="http://amazon.ca">amazon.ca</a>.<br><br><br>The DS18B20 uses the Dallas 1-wire communication protocol which means that<br>many devices can be connected on a string with just two wires. If there is<br>only one device on the bus one instruction is issued to read temperature -<br>Read Rom[33h] . For multiple devices a Match Rom[55h] instruction followed<br>by the 64-bit Rom address of the device whose temperature value is<br>requested.

With a bunch of parts and wires, I made a weather station that shows temperature, relative humidity and barometric pressure. Learning how to make the pixels on a screen go a certain way, writing the program to capture the data and save it or send it somewhere, connecting wires to make something happen. Knowing you did it all yourself. I don't think it's any different than any other creative endeavour. We do it because we find it fun. Why does a chef cook?

Maybe it is not as interesting as I thought. Basically, I learned how to deep sleep a battery powered ESP32. The turkey was unimportant. A very portable device that reports humidity (a cause of mold, for instance, or of hugely expensive water leaks in a condo) and temperature (for cooking, etc) should be in everybody's house, IMHO. The turkey stuffed with micros was a bit of a joke.<br><br>Deid, I like the bead thermistor more than DS18B20s because, waterproofed, I can insert it deep into the turkey breast, for just the right safe temperature without overcooking. Besides, I've got 40 thermistors left <haha>. They worked fine when powered by 3.3v and not a GPIO pin. I suppose I could spare 0.15ma (3v / 20k ohm) continuous drain on the 2600 ma-hour battery.<br><br>On Thu, Dec 17, 2020 at 5:26 PM Michelle Wiboltt <michellewiboltt@outlook.com<mailto:michellewiboltt@outlook.com>> wrote:<br>Ok.
