 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |
Forum Index : Microcontroller and PC projects : Cheap wireless Temperature Humidity sensors

Back in 2018 disco4now (Gerry Allardice) shared a decoder for the Digoo DG-R8S 433 MHz Temperature Humidity sensor which ran quite well on an MM2. I have been using three Digoo sensors reliably since then, but they are becoming hard to get, so I went searching on AliExpress for cheap alternatives. I found a couple which can be decoded successfully with small changes to Gerry's code. I want to share some photos, links and some code, but I have discovered that it got posted when I attempted to save this post as a draft. I will continue with it when I figure out how to proceed. In the meantime, if anyone can tell me where to find help on using this forum, I would be grateful. I'm sorry about the false start! Lew. Edited 2024-11-02 16:12 by LewW |

Personally I wouldn't recommend typing a draft first - you have the option of seeing what your post is going to look like before sending it. You need to use the things like CODE and /CODE to keep your text formatted. Links are posted using the Link button (like an globe with a chain link). If all else fails put the stuff in a zip and use the File Upload button to add it to your post. That gets around odd picture formats etc. providing the zip is less than 10MB.

Hi Mik, Thanks for your reply. Part of my problem seems to be that the link button does not work for me. I can save the link OK, but when I paste it into the link dialogue it does not work. When I paste the same link for Gerry's post directly into the message it looks like the following. It's not pretty, but let's see if it works. https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=17400#229021 Lew. |

That links to this page, sorry. When you press the link button enter the text that you want others to see as the link. Then press OK. In the next box that appears paste in the URL for your link. This is easiest to get by having that page open in another tab and using copy-paste. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I think I see the issue, if you are using the button "<a>Copy link to clipboard" that copies the address of the page you are looking at to the clipboard. As Mick said adding a link is a two step process using the 4th button under "--Font--", after B I U The image upload button, 2nd from right under "--Colour-- v" will accept .PNG and .JPG images. Other formats may need to be converted to one of those first. A quirk of the site is your session can end at any random time, including while typing a long post. You wont know this till you try to save it and it vanishes. To avoid loosing it all first compose it in another editor/word processor then copy-n-paste it. Another option, before hitting "Save Post" copy it all to the clipboard. If your session has ended paste the clipboard in a text editor to save it then sign in again.

Hi Mick and Phil, You have both nailed it! I didn't understand the two-step process, and I was just copying the link into the first box! I can only blame myself for pasting the wrong link though... OK, so I will start again in the next day or so. In the meantime, if you are curious about the link to Gerry Allardice's decoder here it is: Digoo DG-R8S Temperature-Humidity Decoder (433.92 MHz) Thank you very much for your help. Lew. |

Here is something related and it came from "downunder". This is using PIC16 and Oshonsoft Basic to emulate an Oregon Scientific sensor. It can be read with a SDR or a genuine OS console, but I used a WSDL Wxshield attached to an Arduino some years ago. Canberra-THGR810-Clone-v2.1.zip |

OshonSoft brings back a few memories, a brilliant bit of software that I used for maaaany years! I'd be interested to see Vladimir do a sim for mm basic in the same style. Doubtful it would happen, but can always hope... I'm still on the mailing list, so I guess I'm still registered if I want go back to the PIC uController family  John |
