SDS011 sensor does not return data after a few days

awaiting feedback troubleshooting

### PROBLEM DESCRIPTION I'm using a self compiled version of Tasmota (current HEAD), which includes only the sensors SDS011, DHT22, BMP280 and BH1750. After the cold start of Tasmota all sensors deliver values. After about 6 days the SDS011 does not deliver any data anymore. Only a powercycle brings the SDS011 back to life. As hardware I use a Wemos D1 Mini, which is powered by a USB power supply. The SDS011 is directly connected to the 5V from the power supply. ### REQUESTED INFORMATION _Make sure your have performed every step and checked the applicable boxes before submitting your issue.

Perhaps I should have said "how many have not experienced this"instead.

Here the pictures of my installation

Red light on SDS ? Push RST.
And fan noise?

Moebius · November 26, 2022, 4:36pm

It is working now. A power cycle was needed. Installed today a sonoff in another junction box where the cable comes from to be able to remote power cycle for the next time

That looks cool! If you have space in your case, a horizontal orientanion of the SDS011 might save you from a noisy fan later.

Is that a heating element in the inlet? Was this custom?

Moebius · November 26, 2022, 11:28pm

I assume you mean the PCB under the ESP? No this is just a breakout board. The ESP board is just plugged into it. So i can change the ESP board without dealing with cables and connectors.My first plan was to power the ESP also with 5 volt via the breakout board but I got it only running with supplying it via the USB-port. The sensor box lives under my Carport thus I hear nothing from it. On the other hand if there is some Fan noise it not really will bug me

Not the PCB
I mean this.

Oh, this is only Filter with cuttet mesh for PC case fans. I used this part and scaled it down till the silicone hose fits on it. The three rings are for keep the mesh in place.

@Moebius, how much time and effort did you invest in these sensors. I would like to install a similar one…

Moebius · November 28, 2022, 11:54am

This was not a one weekend project If you want to rebuild it I can try to bring together the links to the parts as well as printed parts.

Moebius · November 28, 2022, 6:48pm

I published all things I could find on printables
