I’ve tried the DHT11 sensor modules at both Vcc 3.3V and 5.0V, and at both voltages the humidity values are bad. dfrobot has introduced a V2 DHT11 sensor module that changes the 10K pull-up to 4.7K.

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...

In addition to the NodeMCU board, [Shyam] adds a DHT11 sensor and SSD1306 OLED display. He’s provided a wiring diagram in the repository along with the Arduino code for the ESP8266, ...

To build your very own IoT rain checking system, you will need a Raspberry Pi 3 Model B, a DHT11 Temperature & Humidity Sensor (4 pins), and a raindrop sensing board, which can be purchased for ...

S ummer break is the perfect time to turn curiosity into hands-on learning, especially with a Raspberry Pi in the mix.

First, we need a DHT11 sensor, and to check whether it works using one micro:bit. To do this, we must teach the MakeCode editor new tricks. Go to “Extensions”, type in “DHT11” and click on ...

The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and the speed the motor is currently running at.
