I tried 3 different sensor DHT11 but output is not changed. How can fix it ?
How is your DHT11 connected? A photo may be helpful.
Do you have a 3-pin or 4-pin sensor?
Is it a bare sensor (just the plastic case with leads), or one built on a tiny circuit board?
If a bare sensor, did you add the pull-up resistor? What value and how is it connected?

I tried my dht11 sensor on Ardunio IDE on 5V, it worked. But i cant read on in my particle web ide. I have 3 pin sensor. Maybe is it not working on 3.3V? 
DHT11 does work with 3.3V too.
