I need an Arduino MQTT logger that will read, process, and send data to an MQTT server. The logger will be recording 4-20mA signal sensor data. The frequency at which the logger will record data will vary, allowing for a variable data rate. Other Peripherials are available as (current consumption, temperature sensor I2C, EEPROM I2C, RTC I2C, I/O Expander I2C mainly). If there is no connection to the internet. Sensor log is stored in eeprom. While back online, send data queue packets. Arduino UNO + Ethernet Shield 2 + custom board for peripherals --> connected to ethernet to obtain internet (No wifi) Connect to Hive MQTT Broker online. Skills and experience required for this project: - Proficiency in Arduino programming - Knowledge of MQTT protocol and server integration - Experience with 4-20mA signal sensors - Understanding of data processing and analysis - Familiarity with troubleshooting and debugging techniques - Fixed Price for project. Please provide examples of previous projects or relevant experience when bidding on this project.

Hola Fernando, De acuerdo a los requerimientos de tu proyecto, te puedo ayudar sin ningún problema. Llevo más de 4 años en esta plataforma entregando proyectos de calidad a mis clientes. Entrego en tiempo y en forma. Y puedes ver las reseñas en mi perfil. Anteriormente he trabajado en proyectos similares de IoT y de control industrial con Arduino en donde se requiere un datalogger offline y después enviar los datos cuando el dispositivo se conecta a Internet. Cuento con experiencia en la implementación de cliente MQTT con Arduino usando Ethernet o WiFi. Así como protocolos I2C, SPI, RS323, Modbus y sensores de salida a corriente 4-20mA Me siento afortunado de contar con los skills necesarios y así colaborar para sacar el proyecto adelante. Tengo algunas dudas que me gustaría platicar contigo. Quedo a la espera de tu respuesta! Saludos! Atte. Marco Ciau

Hi there. I have read the project description and I understand that you need to log data using MQTT on Arduino. I am Umer, an Embedded Systems and IOT expert. I have experience in working with Arduinos, ESP32, ESP8266, and other microcontrollers. I have worked with current sensors, temperature sensors, RTC, and IO expander chips. I have knowledge of the communication protocols including I2C, UART, SPI, and I2S. My previous work related to your project: - Sampling the data from 4-20mA signal using the INA219 ADC chip (more accurate way) as well as by reading the voltage across a resistor after passing the current through it (relatively less accurate). - Programming for temperate, humidity, and pressure sensors in a sampling pump and sending data to a mosquito MQTT broker on the server I have all the required electrical equipment in my lab including an oscilloscope, signal generator, and a small-scale PCB prototyping setup. Please drop me a message so that we can further discuss the details of your project. Waiting for your message. I usually respond to messages within 30 minutes. Regards, Hafiz Muhammad Umer Umer Softwares
