We’ll explain how it works, show some of its features and share an Arduino project example … WebDHT11 is small in size with operating voltage from 3 to 5 volts. The maximum current used while measuring is 2.5mA. DHT11 Sensor. DHT11 sensor has four pins- VCC, GND, Data Pin and a not connected pin. A pull-up resistor of 5k to 10k ohms is provided for communication between sensor and micro-controller.

Why does DHT11 need pull up resistor - Sensors - Arduino Forum

WebFirst we need to included the DHT library which can be found from the Arduino official website, then define the pin number to which our sensor is connected and create a DHT object. In the setup section we need to initiate the serial communication because we will use the serial monitor to print the results. Using the read22() function we will ... WebDHT-11 is a digital temperature and humidity sensor. It outputs a much more accurate temperature reading compared to an analog sensor. The output of the DHT-11 is a … how to take out cartilage piercing hoop
