Dht11 digital temperature and humidity sensor is a composite sensor contains a calibrated digital signal output of the temperature and humidity.
The dht11 is a commonly used temperature and humidity sensor.
The dht11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your diy electronics projects.
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 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 sensor can measure temperature.
Dht11 humidity and temperature sensor the dht11 is a basic low cost digital temperature and humidity sensor.
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.
The sensor is also factory calibrated and hence easy to interface with other microcontrollers.
In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity.
