We are looking for someone with experience in hardware designing and development. We have a sensor which with its amplification circuit produces current between 0-200 milliampere. The amplification board is power by a +/- 5V supply. We need hardware development for the power supply and IoT for the board. The power supply needs to be through a rechargeable battery. First, the current by the sensor is directly proportionate to the PPM levels of the gas it senses. We need the results to be displayed on the system and to be transmitted to an AWS server using GPRS. Then, we need a provisioning for two alarms. E.g. 1st alarm at 2ppm and the 2nd alarm at 5ppm. These alarms will be connected to a hooter and LED lights which will turn on respectively when the alarms go off. There should be provision using buttons to change the value of these alarm levels. The sensors too have some calibrations which need to be done, so there needs to be a provision through which we can set the value of the gas at 0 at that specific current. For e.g, the sensor at 0ppm produces 2.23 milliAmp current. Some other sensor may produce 0.23 milliAmp current at 0ppm. So we can initially calibrate the system so that it shows the correct value. This is our requirement in detail. Please contact me for any queries or clarifications.

I am looking for electronic schematic and PCB layout designer experienced using Altium Designer. The project is to develop a carrier board with STM32f4 microcontroller board. On the carrier board, there are electronic cicuits for monitoring temperature sensors, pressure sensors, conductivity sensors, flow sensors, and electronic circuits for controlling selenoid valves, and motors. Prior experience designing with STM32F4 is highly desirable also experience orwith board bring up and troubleshooting the design. This project must be finished in 2 weeks. Basic C programming knowledge is also desired to actually test to run some sample programs on the board.
