You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD. In my case I chose the serial monitor version because is faster and cheaper, but you may want to look at other articles, including this one, if you want to use an LCD.

http://www.aosong.com/en/products-22.html WebThe DHT-22 (also named as AM2302) is a digital-output relative humidity and temperature 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. In this tutorial you will learn how to use this sensor with Arduino uno.

WebConnecting a DHT11/DHT22 sensor to an ESP8266 is pretty easy. Begin by placing the ESP8266 on your breadboard, making sure that each side of the board is on a different side of the breadboard. Place the sensor on your breadboard next to the ESP8266. Connect the sensor’s VCC pin to the ESP8266’s 3.3V pin and ground to ground. Web18 dic 2014 · The AM2302 has a built-in pull-up resistor, whereas the DHT22 does not. Apart of that and de different housing they should be technically identical.
