Description:
The DHT11 Sensor Module is a commonly used temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data.
The Humidity And Temperature Sensor is also factory calibrated and hence easy to interface with other microcontrollers. The sensor can measure temperature from 0°c to 50°c and humidity from 20% to 90% with an accuracy of ±1°c and ±1%. So if you are looking to measure in this range then this sensor might be the right choice for you.
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).
The High-Precision DHT11 Sensor is 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.
