Description
Electronic for No Humming
To prevent humming, capacitive reactances are used to limit the current in the motor stator, and since the friction (blades etc) is moderately high, the rotation speed decreases. This version has four speeds to keep the form factor as small as possible, (capacitors and relays are large).
IOT Control
To control the device from a cell phone, Espressif Rainmaker is used, which has an application for android and iphone, which allows you to configure the Wi-Fi network (provisioning), and control the device through the AWS IOT.
