Hello, I am a beginner in node red and would like to save the data from the dht22 sensor in mysql and display via chart. I have already tried a lot but unfortunately without success.
@tnick STM32F1 2019.12.8 (stm32duino) is the version that was active when the latest MySensors release was made. Later versions may or may not work; nobody would know until they tried.
You write "...clicking is heard..." Is that a single click or a click click click ...?
After getting the LOW signal, wait a period of time and if it's still low, send the message that there is a flame. Likewise for a HIGH signal.
Perhaps instead of a relay, an opto-isolator?
Update and problem fixed!
For everybody that will encouter this, the problem was at the sensor side because of the folder of the sensor! We created some metal brackets for it and they where exactly the same diameter. The fact that the mount squeezed the sensor made it return the lowest value.
Just needed to adjust the hole and everything was ok!
