In this instructable we are going to learn how to monitor the temperature and the humidity measurements using the IOT-MCU/ESP-01-DHT11 board and the AskSensors IoT Platform.



I'm choosing the IOT-MCU ESP-01-DHT11 module for this application because it's ready-to-use and save development time. However, if you are looking for home automation systems, I suggest the ESP8266 nodeMCU tested in my previous instructable, which provides more input/outpout, large memory and additional features.

ESP-01 OVERVIEW:

The ESP8266 is a low-cost WiFi module with full TCP/IP stack.

The ESP8266 series are produced by Espressif Systems.

The ESP-01 is a small size black colored module with 1M memory.

Note that the ESP-01 module requires only 3.3 volts to power up.

IOT-MCU ESP-01-DHT OVERVIEW:

This module uses the ESP-01 or the ESP-01S as the master control, and the DHT11 allowing to measure the in the scales from 0 to 50 degrees Celsius and the humidity of the air in the ranges from 20 to 90%.

As follows a summary of the main characteristics:
