I have purchased 5x of these ([login to view URL]) C2H3CL-20 sensors and I would like to get a board that does the following things: 1. provides a solar panel input of 12v and charges a lipo 2. uses the lipo wake up a microcontroller (esp32 would be good) which would: 2.a: sample from a front end w the above sensor 2.b: store the sample on flash storage 2.c: send the data to a basic webserver or mqtt server or whatver 2.d: sleep again Kindly select the components, capture the schematic and lay out the board, take the lead on firmware, and work with me through the testing i would be happy My goal is to open-source this design and to hand these sensors out in response to the environmental disaster in Ohio in the US. I have a bunch of experience deploying sensors so I can hopefully help out a bit (or at least not get in the way with crazy features)... but if you can pull this off I would love to use you for many more small projects like this! I would hope to print boards in the next couple weeks and then have firmware ready by mid march at the latest. I will want you to also provide a case design I could laser cut that has the right considerations for airflow and fits the battery, has a port for the solar panel, etc... Thank you! I really look forward to working with you!

@PCBDESIGNER38

Hi, Hope you are doing well. I am interested in this PCB design project. I have experience with Altium, Eagle, KiCAD, and EasyEDA software tools. I have completed several PCB layouts based on microcontroller, Power supply, SMPS, DC-DC converter, RF, and impedance-matching PCB layouts. I have great control over impedance calculation for RF PCB design. I have expertise in interfaces like SPI, I2C, UART, USB, RS485, and CAN. Furthermore, I have a good grab on Firmware development for ESP32, Atmel, Microchip, STM32, Raspberry PI, nRF51 & 52 microcontrollers. What you will get from me; Source Files(Schematic, PCB layout, PDF, and DRC File) Manufacturing files(Gerber FIles+NC Drill FIles+Pick and Place+Bill of materials(BOM)) Why choose me; PCB layout always maintains the standard manufacturing rules After completing the PCB layout, all the designs will go for several times electrical rule checking. And, I always try to make it 100% error-free. I will provide the manufacturer standard PCB files, such as JLCPCB, PCBway, nextPCB, Colorado PCB, PCBhero, etc. Regards, Raseduzzaman Ruman
