In this instructable we are going to learn how to monitor the temperature and the humidity measurements using the IOT-MCU/ESP-01-DHT11, MAX7219 LED matrix display.
ESP-01 OVERVIEW: The ESP-01 is a small size black colored module with 1M memory. The ESP8266 is a low-cost WiFi module with full TCP/IP stack. The ESP8266 series are produced by Espressif Systems. Operating voltage: 3.3V volts.
IOT-MCU ESP-01-DHT OVERVIEW: Controller: ESP-01 / ESP-01S (To buy separately) Temperature and humidity sensor: DHT11 Operating voltage: DC 3.7V-12V (It supports 3.7V lithium battery power supply) Measuring range: 20-90% RH 0-50 ?, Measurement accuracy: Temperature ± 2 ?, Humidity ± 5% RH.

ESP8266 ultrasonic distance measuring Displayed on MAX7219 Dot Matrix
In this Arduino Tutorial we will learn how the HC-SR04 Ultrasonic Sensor works and how to use it with the Arduino Board. You can watch the following video or read the written tutorial below.
The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig and Echo. The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the esp8266
