Connect your ESP8266 to any available Wi-Fi network


The ESP8266 is a microcontroller developed by Espressif  Systems. Known as a WiFi Module, this microcontroller has the ability to perform WiFi related activities like Internet of things applications and home automation. Ranging in price and features, there are many types of ESP8266 modules available, but all of them are incredibly useful for IoT world.

Regardless of the IoT application you’ve developed, when using the ESP8266, you must set the WiFi credentials into the ESP8266’s firmware to establish the required connections and be able to send data to the cloud. This is one way to connect, but you can also build your own access point into the board making an universal firmware which will establish a connection in any network available just by pressing a button.

Build a Tank Volume Reader for Under $30 using ESP32

The Internet of Things has brought a lot of formerly complex device applications into the homes of many craft brewers and wine makers. Applications with level sensors have been used for decades in large refineries, water treatment plants, and chemical plants. With sensor prices falling, now both industrial and DIY can monitor the volume of any tank, barrel, or canister.

The sensors available on the open market can sense most anything and are classified accordingly. Sensor used for measuring humidity are termed humidity sensor, pressure called pressure sensor, distance are called position sensors, and so on. In a similar fashion, the sensor used for measurement of fluid levels is called a level sensor.
