017 - ESP32 MicroPython: DHT Values Auto Updates using AJAX

In this video we will learn to create a web server hosted on ESP32 and display DHT measurement readings on it. We will use AJAX to automatically update the sensor values without refreshing the whole web page.

Of all of YouTube and of all the web, your video was one of the best examples of ways to use AJAX in the ESP32. Thank you very much for making this tutorial. You just got a new Subscriber:)

If any one got error try this
if update == 6:
try:
d.measure()
t = d.temperature()
h = d.humidity()
response = str(t) + "|"+ str(h)
led.value(not led.value())
except OSError as e:
print(e)
print('dht_sensor Reading Failed')

else:
response = web_page()
