WebJul 16, 2024 · The DHT11 Sensor is factory calibrated and outputs serial data and hence it is highly easy to set it up. The connection diagram for this sensor is shown below. As you can see the data pin is connected to an I/O pin of the MCU and a 5K pull-up resistor is used. This data pin outputs the value of both temperature and humidity as serial data. WebAt the start of line 6, there's a type issue with "t". When you're declaring a new variable, the thing that always comes first is the type (like 'int' in "int myNumber = 3;"). In this case, you forgot to say what type t is, as if I'd said "myNumber = 3;". The compiler has no idea what 't' is - it's not a type, and this is the first mention of it.

"WebPower: the DHT sensor has an operating range of 3V to 5.5V (DHT11) or 3V to 6V (DHT22). If you’re powering the sensor from the ESP32 3.3V pin, in some cases powering the DHT with 5V solves the problem. Bad USB port or USB cable: sometimes powering the ESP32 directly from a PC USB port is not enough. " - Dht11 does not name a type
