TheDHT11is a commonly usedTemperature 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 is also factory calibrated and hence easy to interface with other microcon...
With the SenseCAPS2110 controllerandS2100 data logger, you can easily turn the Grove into a LoRaWAN® sensor. Seeed not only helps you with prototyping but also offers you the possibility to expand your project with the SenseCAP series of robustindustrial sensors. ...

wiki:This Arduino DHT11 temperature and humidity sensor has a full range temperature compensation, low power consumption, long term stability and calibrated digital signal.
Using the Data in Other Programs What if you don’t want to output the actual humidity and temperature readings, but need them to calculate or control other things? The code below is the bare minimum needed to initialize the sensor. You can add this to existing programs and use DHT.humidit...
This will make the data appear correctly for the correct sensor. Upload the sketch! You should see the temperature and humidity. You can see changes by breathing onto the sensor (like you would to fog up a window) which should increase the humidity. You can add as many DHT sensors as yo...
