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.

The build runs on an nRF52811 microcontroller, hooked up to a 1.02″ ePaper display sourced for just $7. A SHT20 temperature and humidity sensor is then queried to sample the ambient conditions ...

This week, our mini weather station will measure temperature and humidity. And by using a second BBC micro:bit, we can get the readings before heading outside. First, we need a DHT11 sensor, and ...

Dual LCD Displays: Time and temperature on the top LCD, menu and status on the bottom LCD. DS3231 RTC : Accurate timekeeping with battery backup. DHT11 Sensor : Temperature monitoring in Fahrenheit.
