IOT application

Pls, check my feedbacks, which also include IoT projects. Larger one done directly with clients under NDA. Unfortunately, your budget is too low for German engineering.

Hi , Trust you are doing well ! I have 10+ years of experience in embedded products development. I have expertise in IoT products development based on different wireless technologies i.e. Wi-Fi, BLE, GSM/LTE/NB-IOT, LoRa, GPS, ZigBee etc. Key skills: - Proficient in PCB design up to six layers using various design tools - Hands on experience on IoT design/development and deployment - Experience in Embedded Firmware development and porting for any new architecture and new hardware platform - Hands on experience in the design, implementation and maintenance of embedded hardware and software/firmware development projects - Protocols (SPI,I2C,UART,CAN,TCP/IP) - Sensors integration (Acclerometer,Gyroscope,Inclinometer,Temperature,Humidity,Pressure,Heart rate, Load Cell, Ultrasonic etc.) - Batteries optimization(LiPO,LiIon,Alkaline,AA,AAA,18650) - Power supplies (LDO, Switching regulator, Buck-boost converter, battery charging, PMU) - C, C++, Python, Shell - Over the Air Firmware Upgrade I have recently designed similar kind of products using BLE Chipset (nRF52840 as MCU), LTE CAT M1 module (Quectel BG96 ), MCP9808 Temperature sensor, BME280 humidity sensor, RGB LED and Battery with USB charging. The moto of this product was to fetch sensors data at particular time interval, store them to MCU's internal memory with timestamp and send them to AWS IoT Cloud using MQTTS. I have also worked on SIMCOM LTE module(CAT M1 and NBIoT). Let's have discussion. Thanks. Jitendra

Hello, I can suggest you the best H/W platform. I have experience working with GPS receiver, Temp sensor, LTE modem, Cloud communication, MQTT protocol, PCB design, Code-Firmware implementation.

If u are ok we can use rp2040 and micrpython. ............................................................esp32 also can be used

I am IoT expert I have already developed similar system . I can show you demo . The hardware used are esp32, sim800l , hostinger cloud hosting , MySQL database. Dashboard to monitor the data in graph .

Hello, I have done similar projects connecting to PLC's or TCP/IP devices. Please call me to discuss further. You can see an example in my portfolio for a web interface reading scale data from a RS232 to Ethernet converter. Also have done connection to a PLC read tags and send data via MQTT to an MQTT client in the Cloud. Regards, Alexandros

Hi I have more than 8 years experienced in circuit design and development in my past I have designed lot Iot board for company I can designed best ways Dee emiemc

I'm an italian electronic engineer with more than 18 years of work experience. I work as HW designer and FW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC, ARM Cortex, ESP32) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Eclipse + GNU ARM GCC for different ARM Cortex M0/M0+/M3/M4/M33 manufacturers (STM32Fx, NXP, EFM32/EFR32 SiLabs, Nordic nFR5x, but I'm ready to learn new frameworks). I have also good experience with ESP32 in "esp-idf" framework. I work with both single task (bare metal) and multi task environment (FreeRTOS, RTX,...). I write code for low level driver (GPIO, UART, SPI, I2C, PWM....) management, for medium level (driver for sensor, MEMS, memories, fuel gauge, display,...) and for high level/final application, for bootloader and for OTA. I have great experience in cloud communication with MQTT/Azure protocol. I work also in "C code" commercial boards Arduino/Linux embedded commercial boards (Raspberry and Beaglebone). I have experience in bluetooth (both 2.0 and 4.0) programming.

I am now working as a software engineer in dotnet platform, and I had worked in Arduino, nodemcu project also. I had also done a iot home automation system using rabbitmq broker
