Dht11 Arduino Kullanımı. Please refer to 3 of conditions minimum typical maximum power supply dc 3v 5v 55v current supply measuring 05ma 25ma average 02ma 1ma standby 100ua 150ua sampling period second 1. A 10k ohm pull up resistor is needed between the signal line and 5v line to make sure the signal level stays high by default see the datasheet for more info.
Create a dht object that refers to the sensors data pin in this case its gpio 14. Then we will click on the add device which will be used in this project as we are using nodemcu esp8266 so we will select esp8266 and add then select nodemcu and click on the continue. Set the baud rate of serial monitor to 9600.
5v supply is recommended although the supply voltage ranges from 33v to 55v.
You will need to make some extra connections to the arduino so we can control the 162 character lcd. Project showcase by mako. The dht11 or dht22am2302 sensor is connected in the same way as before. The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.
