Random peaks in DHT11 sensor

Post by Bldjef » Friday 22 September 2017 9:32

Hi,

I've succesfully installed this DHT11 sensor on my Raspberry Pi 3B (with the help of this topic).
The only problem I got is that the temp and hum randomly peaks to weird numbers like 9 degrees.
Because I later want to use this temp sensor to control my heating, I would like to fix this.

I also got this problem when I read the data with a shell command, so it's not a domoticz issue.

Does anybody know the solution for this?
Thx!

I have the same issue... so it's not your setup...

I have read somewhere else that the DH11 is a cheap so no good sensor.

I think the only solution could be to make several reads, calculate the right value (removing this peaks) and then send the data to domoticz

Thanks, I thought I bought a nice decent sensor and not one from Ali shops :roll:
