I need to connect two gas sensors to one arduino, power them with one battery, and let a group of such Arduinos send their gas sensors' data to the computer wirelessly and simultaneously. The following components have been chosen by me: 1. Arduino Nano 33 BLE 2. Sensor A (3.3V TTL level RS232, supply vol 4.5 - 5.5 V), sampling rate 1 reading per second 3. Sensor B (3.3V UART), sampling rate 1 reading per second 4. Nordic nRF Connect (optional) 5. NRF52840 dongle (on PC to connect arduinos) 6. Battery 20,000mAh. You will need to help me provide, 1. code the Arduino to send gas sensors' data to one computer simultaneously 2. set up the nRF connect (or other portals) to be able to record data from a mesh of the arduinos (e.g. 15) 3. optimise the battery life to let each arduino collect the sensors' data for 2 months and send the data to computer at the same time The final work will be like, 1. one arduino and two sensors powered by one battery to form one cluster with a sampling rate of 1 reading per second 2. a BLE mesh of these arduinos to connect to one PC (NRF dongle) wirelessly 3. PC records data from arduino A, arduino B, arduino C,..., arduino Z 4. each cluster can collect gas sensors' data for up to 2 months I have chosen the above components after my research. You don't need to purchase anything except help me with the above. Thank you.

Hello, thank you for your job posting. I read your description about--Arduino I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

Hi, I am Mykyta, I am an firmware developer who are familiar with arduino and C Programming I read your proposal carefully and got what you wanted. In the past, I have implemented temperature and humidity data measuring and transferring using esp32 I have some knowledge about the NRF, BLE and sensors. These points will implement your idea successfully, I think. I have enough time to work for your project now and skills and wills to progress your project successfully. You will get good results working with me, I think Looking forward to hearing from you Best regards, Thanks

Hello sir, i'm embedded systeme engineer, i think it would be really slow if you use bluetooth because its p2p and require Handshake before transmission, what about using HTTP requests and have results in website instead of computer, or just using Wifi ? i would be happy to discuss this project more with you cordially

Our team is experienced in working with IoT based applications. We have worked on projects which involved integration with different sensors ,wireless modules and different interfaces like RS 232/485. Therefore we can provide you an efficient and low powered solutions on time with optimized firmware in C or Arduino IDE (whatever the requirement may be). We can design professional level PCB circuits and generate all relevant manufacturing and assembly files including Gerber and BOM. We can further discuss the project in detail.

@valmarssilva

but from what I understand you want to make two sensors connected to the Arduino and connected to the PC with a Bluetooth sensor, these sensors will send a sampling of 1 second. I am interested in executing the project, the source code with a sample example.
