DHT11 temperature and humidity sensor~ DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It is very inaccurate and surpassed by others (AM2301, BME280, ...) thus not recommended by us. Configuration~ Wiring~
DHT11 temperature-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). Its fairly simple to use, but requires careful timing to grab data.
Jul 18, 2018· 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…
May 06, 2021· Question: does the DHT11 work, that is, does it produce meaningful humidity information in Serial Monitor? In your original post you say you connect the data wire from the DHT11 with pin 2 of the Arduino, while the sketch says "#define DHT11_PIN 7" -- this means that you should have the data wire from the DHT 11 …
