You may also want to try powering the DHT sensor from 5V (we found sometimes it really needs more power) but still having the 10K pull-up resistor to 3.3V volts) Now create an instance of either theDHT11orDHT22class, depending on the type of sensor you're using (for the AM2302 sens...

The delay is there for a reason; the DHT22 requires two seconds between readings for the sensor to stabilize. Fixing this isn’t easy, so I’m not really blaming ChatGPT. A proper fix would have the DHT22 being read using a 2-second timer interrupt or a counter that counts elapsed mi...

We first execute the project with the traditional implementation using the C++ language, with a program to read the sensor data and then verify the environmental conditions. We can realize this application with a simple MCU. For this example, we will use theArduino UNO R3, connected to aDHT22...
