Module of Air Conditioning
Embedded Systems & Microcontrollers
The air conditioner control module has two main functions:
1) the function of the thermostat - the tracking of the indications of the thermostat and the response of the system when the temperature of the specified installations is reached.2) the transmission of the IP package of data (command for the air conditioner).The device is built on the MC stm32f103c8t6.From the external components to work it requires the connection of the thermodator (ds18b20 or ntc thermistor) and the IC LED (for the radiation of the IC commands).T K .The device was developed remotely without physical access to the air conditioner (and also in the requirements was a condition of compatibility with EVERY air conditioner), the IC receiver TSOP31238 was installed for receiving commands from the home air conditioner.The algorithm of the program allows you to take (and keep in the PCU for further reproduction) the IQ of the team of EVER(!)A protocol with a length of 0.05 ms to 65 ms and a length of 1 to 400 bits of data.The o.The developed device is "trained" and can be adjusted to work with almost any home air conditioner (principally with any device controlled by means of ICT transmission).Working with the device (his configuration) is done using the buttons and the seven-segment indicator set on the payment.

Control of step-by-step engines with smartphone
Embedded Systems & Microcontrollers
The program is developed under esp8266, as well as an Android application.
The Android app allows you to control two step engines connected to the payment with the IC. When you press the button on the smartphone, the engine begins to rotate, when the button is released, the engine stops.
The system has 2 engines (28byj-48 and 17hs4401)
#sp8266 #Android #stepmotor
… In the application window there are the buttons to control each of the engines separately (speed and rotation direction task)
Additionally, it is possible to scale the system (in the program for esp8266 is encrypted a unique system ID, which must be indicated in the application for the smartphone)

The Heater Control Module
I’m working with Alexander for the second time and I’m going to talk to him in the future. Everything in the best way. help with the accurate formulation of the TZ, performed all the work in time and the result fully justified expectations - the performance of the received device strictly meets our requirements.
I recommend

Development of the Air Conditioning Control Module
A competent and responsible executor.
He asked a lot of different questions about the project, which eventually get the most accurate TZ.
The work was performed a week before the agreed deadline. All the work was done remotely, after it was completed, I received a video report on the work of the device, which was then sent to me to the city by new mail.
During the course of the work Alexander himself decided all issues on the purchase of components etc.
I highly recommend this executive as an electronist, a programmer.
