IOT MCU ESP 01 DHT11 & MAX7219 LED Matrix Display


  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.

  1. Hello

    my project is to make a dehumidifier box ,with dht11, Tm1637 and arduino nano ,i search a lot in youtube and google ,but I can’t find what I was looking for,{ I need a setting , to set the relative humidity manuly ,by setting with set push button and value up and down botton ,total 3 botton need , when set Value (humidity ) reached ,the relay must off and other wise on ,so i can connect to pelter plate and also I want to bilink the humidity value blink when it set button pushes please make this program code for me, to rithikadithi@gmail.com
