Hardware design, making cum embedded programming project

Please bid including the hard ware components price for 5 sets of devices
Part-A work :

1. Inside steering we are putting three sensors-(i) Finger Print sensor (ii) Alcohol Sensor (iii) Health Sensor. MQ-3 module is suitable for detecting Alcohol. The MAX30102 is an integrated pulse oximetry and heart-rate monitor biosensor module. FPC1020A is a secondary development module for fingerprint recognition.
2. All their data has to be periodically send to our Cloud Server (AWS or Azure Cloud ) through a IoT Gateway device. 3. Hardware has to be designed end to end including power connection part and communication part. 5. Project includes first 2 sets of hardwares to test and then subsequent 3 more sets of hardwares for commercial use. After completion of this project, the future hardewares need can be sourced from the vendor

Our made part : We have already done some part of embedded programme and code.

Your task is -- 1. You have to integrate with third party finger print solution integrating with our cloud. 2. to make it more commercially deployable in mass scale robust and scalable way. You can use our already developed code, components and design for speedier and better result.

Part-B work :

If you want to your IoT Gateway device, then it should have the following feature --

1. That IoT device must act as OBD II protocol J1939 commercial truck data reader through wireline or Bluetooth connection .
2. It must have quality of driving sensor chip in the IoT device which can check driver's sharp turn, hard break related vibration and reckless unstable driving sensors.
3. That device must collect the data from SmartSterring sensors data and must transfer data to Cloud Server as well as some data to the Android or Window Tab attached to the truck dash board through blue tooth or WiFi connection.
4. It should have enough back up memory to save data for 12-24 hours in case it failed to get any 3G/4G connection.
