DHT11 Humidity Temperature Sensor


Rela ve humidity largely depends on temperature. Although temperature compensa on technology is used to ensure accurate measurement of RH, it is s strongly advised to keep the humidity and temperature sensors working under the same temperature. DHT11 should be mounted at the place as far as possible from parts that may generate heat. (5) Light ect

How to connect DHT11 Sensor with Arduino UNO Arduino ...


15/5/2020· DHT11 Sensor. The DHT11 is a basic, ultra 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.
