More than 9 DHT sensors

Hello,

I tried to search internet, but had no luck.

Is it posible to connect for example 30 units of DHT11 sensor to one Arduino Uno board?

I read about shiftin, but cant find how to use it with DHT.

No, because you need a separate pin for each DHT11 sensor and an Arduino UNO has (at most) only 20 GPIOs available.

What are you trying to achieve? Maybe there is another solution for your problem?
