DHT11 basic temperature-humidity sensor + extras
The DHT11 is a basic, ultra low-cost digital temperature and humidity
sensor. It uses a capacitive humidity sensor and a thermistor to measure
the surrounding air, and spits out a digital signal on the data pin (no
analog input pins needed). Its fairly simple to use, but requires
careful timing to grab data. The only real downside of this sensor is
you can only get new data from it once every 2 seconds, so when using
our library, sensor readings can be up to 2 seconds old.
to the DHT22, this sensor is less precise, less accurate and works in a
smaller range of temperature/humidity, but its smaller and less
Comes with a 4.7K or 10K resistor, which you will want to use as a pullup from the data pin to VCC.
