The “List of Parts Required” for “Learn ESP32 with Arduino IDE” has on Page 1 the list of parts for Module 1 to Module 6. I am currently looking to start Module 5, Unit 5 with requires a DS18B20.
I don’t have one because it was not mentioned on the list of required parts at the time I began the course. I see that now it is on the list!
These are the additions since I first printed my list:
• DS18B20 temperature sensor
• I2C 16×2 LCD
• Raspberry Pi board
• MicroSD Card – 16GB Class10
• Raspberry Pi Power Supply (5V 2.5A)
I’m now wondering what else may be required and not on the list?
It will take some time to get delivery on this item, meanwhile, does it make sense to try one of the other temperature devices on the list (as a temporary solution only)?
These others are: the BME280 and the DHT22 parts.
I suspect the answer is YES, go ahead with one of the others and I think this because of this statement on the “Make Advisor” web site:
“You can compare different temperate sensors to find the best one for your project: DHT11 vs DHT22 vs LM35 vs DS18B20 vs BME280 vs BMP180“.

Hi Ray.
The parts you’ve mentioned are already on the list in the latest version of the eBook, which is version 2.1.
You can download the latest version on the course dashboard: https://rntlab.com/module-1/learn-esp32-welcome/
Yes, you can proceed with a different temperature sensor as long as you use the right methods to read from that sensor.

Sara

Thanks, Sara.
I just ordered a DS 18B20.
I bought the waterproof one because it was cheaper (cost + shipping) than any others I found.
I’m going to wait for its arrival before continuing with that Unit.
Meanwhile I also bought a carrier board for the RFM95W. It’s from Tindie. I can continue with the LoRa Unit because I also took delivery the other day from Adafruit of 2 of their RFM95’s which come on a carrier board.
So, I can continue with the Adafruit units while I wait for my Tindie boards so I don’t have to fiddle around with how to make the RFM95W (with 2 mm pitch) work on a breadboard.

Hi Ray.
That’s a good solution for those modules.
Wiring the RFM95W module directly to a breadboard is not an easy task.
I’ll mark this issue as resolved.
If you need further help, you just need to open a new question in our forum.
