ESP32 Module Application and Project Practice
Posted: May 02, 2017
ESP32 is a latest low-cost and low consumption wifi module, Bluetooth, double processing chip. It has power performance, RF performance, stability, versatility and reliability and suitable for a variety of applications and different power requirements. In addition, it was designed for mobile devices, wearable electronic products and internet of things applications. The module is generally applied to wifi audio solution, wifi mini camera, 3D games, mesh networking, intelligence home and mobile networking, etc. You can buy ESP32 Module at the Elecrow online store and I believe it will give you a good experience. Click to buy https://www.elecrow.com/esp-wroom-32-esp32-wifi-bt-ble-mcu-module.html Next, I want to share four projects about ESP32 with you that “ESP32 Arduino IDE "Hello World" ”, “Indoor Air Quality with ESP32”, “ESP32 touch controlled led using Arduino IDE “ and “ESP32 WiFi Range Testing - 10km using Directional Antenna”.
In this video, you see the Hohenneuffen castle first that the distance from the camera about 10km and the video mainly about the developer who using the ESP32 use the ESP32 chip to connect a camera module and a directional antenna to achieve 10km photo transmission.
First, use the Friis Equation to estimate the intensity of receipting the signal.
Second, additional use some similar USB WIFI adapter receiver and 2.4GHz directional antenna.
Third, as long as manual the antenna toward to the direction of the castle, we can get the signal strength we want.
Although the transmission of the picture quality is not very good, it is no problem that accepting the ESP32 chip sent outside signal in the 10km. At last, enclosed a working principle diagram of the ESP32 using Bluetooth function to assist WIFI connection to the router.
The above is an only part of the application of ESP32 projects, if you have more ESP32 projects or DIY ESP32 projects, you can also share with us.
