Measure Humidity and Temperature with DHT11 Sensor ...

· The DHT11 sensor consists of a humidity sensing component, an NTC temperature sensor (or thermistor), and an IC on the backside of the sensor. The term "NTC" means "Negative Temperature Coefficient", which means that the resistance decreases with the increase of the temperature. Also, It has an extremely accurate calibration of the humidity calibration chamber. Its …

DHT11 Humidity and Temperature Sensor

DHT11 Humidity and Temperature Sensor The DHT11 is a basic, lowcost 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). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can ...

DHT11 Temperature and Humidity Sensor With Arduino techZeero

· The DHT11 Temperature and Humidity Sensor senses, measures and regularly reports the relative humidity in the air. It measures both moisture and air temperature. The warmer the air is, the more moisture it can hold, so relative humidity changes with fluctuations in the temperature. Humidity sensors detect the relative humidity of immediate environments in which they are placed. They …

DHT11 temperature and humidity sensor Tasmota

From the Wemos DHT11 shield specs the DATA OUT pin is connected to D4 of the Wemos. Note: Having the shield compact on top of the processor increases the temperature. In normal Mode this can be up to 6°C. So you should add sleep mode. Adding normal "Sleep 100" and putting the sensor vertically reduces the temperature difference to 2°C.
