I'm working for 10+ years as an electrical and electronics engineer. I can menage your projects, design your pcbs, write necessary embedded software, design interface softwares for windows, linux and android.
I can select all the components for your project. I can use all kinds of sensors ie temperature, light, pressure, accelerometer, gyro, proximity, infrared, pir, hall effect, gas, ultrasonic, current almost whatever you can imagine. They can be SPI, USART, CANBUS, 4-20mA, 0-10V does not matter.
I can use gps(gnss), gsm, gprs modules and make tcp/ip connections, i can use bt/ble, lorawan, wireless connections and modules.
I can design your HMI graphics, and use embedded hmi solutions (such as ssd1963 etc).
Just imagine.
