ESP-01 with ES8266 chip: small but powerful WiFi module for your Arduino project!

Continuing from my last post about Homemade weather station , today I will dig deeper in ESP-01 WiFi module, Lets begin! The ESP8266 is a low-cost WiFi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems. More information about this module u can get from Wikipedia . To use this module,

Temp and monitor and alarm system for your environment. I have a small server room need to monitor 24/7 and alarm when humidity, temperature go over a fixed value: like 25 C degree and 70%.   Arduino Uno R3 may be the most popular open source hardware with lots of modules following. ESP-01 is the cheapest wifi module, DHT 11 . Here is my codes: /*--------------------------------------  * Getting temperature and humidity from DHT 11 and upload to thingspeak.com  * You get this code from https://lotus-vp.blogspot.com ,  * please keep these comments when copying these code, thank you!  * Connections  * DHT         | Arduino Uno  * ---------------------------  * VCC(1)    |  5V  * DATA(2)  |  2  * NC(3)       |  x  * GND(4)    |  GND  -------------------------------------*/ #include <Sof...
