Misting Controller,Hybrid Mobile App and Cloud App Development on MVP Basis
The product is a misting device that produces the mist with a rotating cup (brushless motor) and the water is fed into the rotating cup via a water pump (stepper motor). The misting device is designed to come on in set intervals, e.g. 10 seconds every minute, but is changeable by the user.
The challenge was to improve the function of the device, the rotary atomiser turns on for about 1 second (can be changed by user) before the water pump switches on and then the rotary atomiser turns off 1 second after the water pump switches off (can be changed by user). There is also a high voltage module that turns on at the same time as the rotary atomiser which makes the mist negatively charged.
A high level architecture of complete system was made along with the list of devices and resources needed. STM32 Firmware was used for speed controlling, ESP32 Firmware was used for control and monitoring sensors. Mobile app was made on React native and a cloud app was made for reports and status updates.
STM32 Firmware
Xcode
ESP32 Firmware
Android Studio
From the development front, we segregated the system into individual features. We then developed and tested them individually before moving on to the next feature. During every stage of the development process, our client, development, designing, and the testing team was continuously kept in the loop.
