Problem with Temperature Sensors

[Diego Palacio]

First of all, hello to everybody in special to Fernando. Congratulations and thanks for your hard work.

The problem I have is that during light (sunrise starts at 8:15 and night starts at 21:45) time (when lights are off they work properly), temperature sensors decrease (or in any moment do not give signal) somo degrees.
Attached are some charts to show that.

This other are from when I only have 2 sensor connected:

It give me some problems because fans stops when they must run, heaters starts when they do not have...

If, for example,When I see a uncommon temperature (from LCD or via web), if I go to temperature sensors, they continue with wrong value but if I serch for them, the correct value appairs again.

Could you help me??

Hi!

Welcome Diego!

Seems electric noise.

Which circuit are you using for fans and LEDs?

Try connect the fans in a power supply individually without speed control to see if it works better.

Best regards.
