DHT11 interfacing with Arduino uno

In this tutorial, we’ll learn DHT11 interfacing with arduino uno. DHT11 is a low cost sensor (temperature and humidity) which can be used for less precise application. you don’t have to calibrate these sensor. because these sensors are calibrated by manufacturer itself.

Materials required

  • Arduino uno
  • dht11 sensor
  • Resistor
