Review on MakerFocus 2Pcs ESP8266 ESP-01 Serial Wireless WiFi Transceiver Receiver Module 1MB SPI Flash With DHT11 Temperature And Humidity Sensor Module For Arduino by James Wickware

While doing small DIY projects I didn't realize what I was missing until I discovered this one. If you want to control something wirelessly, such as For example, an LED, you typically buy a $20-$30 smart plug and a power supply to plug in, which will eventually control your LED or motor. With this module you can create a reliable and secure remote managed application in just a few hours. With Arduino Studio and other free software, you can quickly build all sorts of smart things and eventually connect them to any home automation hub (I have Wink), Alexa, or whatever. Another great advantage of these devices is that they don't need a specific manufacturer's cloud and app to work - just connect to your WiFi and get the job done.
