It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems.
Dht11 digital temperature and humidity sensor is a composite sensor contains a calibrated digital signal output of the temperature and humidity.
Dht11 humidity and temperature sensor the dht11 is a basic low cost digital 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 sensor can measure temperature.
The sensor is also factory calibrated and hence easy to interface with other microcontrollers.
