DHT11 Humidity and Temperature Sensor
The DHT-11 Digital Temperature And Humidity Sensor 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).
It's 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 in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate, and works in a smaller range of temperature/humidity.
But despite its disadvantages over DHT22, it is a smaller and less expensive sensor for temperature and humidity measurement.
APPLICATIONS:
• Measure temperature and humidity
• Local Weather station
• Automatic climate control
• Environment monitoring
Also check the DHT11 Humidity and Temperature Sensor Module pack of 25, The module operates in the voltage range of 3.3VDC to 5.5VDC and is described as a basic, ultra-low-cost digital temperature and humidity sensor.
