# Question List

1. What sensors are existing?
2. What are the sensors' usage?
    2a. are there any side effects of the sensors?
3. Sensors coverage?
4. How to power it? Just using the power supply provided to power it?
    4a. Is there any other way not using the original power supply to power it?
5. How to communicate with the device?
    5a. Using what protocols to communicate with the devices / device's register? Like I2C / Modbus?
    5b. Is there anyway to convert I2C to Modbus? Or the devices can convert the signal one protocol to another protocol
6. How to get the data?
    6a. How to get the sensor data
    6b. What are the sensor data's data type? small int? big int?
    6c. Is there any data format convertion that we need to handle?
7. Do you know how to use the data logger?   
    7a. If you know, do you know how to make these sensors to communicate with the data loggers?
8. (If there are temperature sensor) Do you know how to allign the temperature sensor in some specific location? (i.e: Walk-in freezer)
    8a. Is the height of sensor would affect the data very obiviously of the above case?
9. I2C data format !!!!!!!!

<h1>
Friday 3:00pm Zoom Meeting
</h1>

Comp -> modbus
Firm modbus
Or still comp other protocol
Or still can both UART and modbus

And then after mid-autumn fest burn the firmware of the MCU

Ask the vendor for the data logger arrival date.

# Next face meeting
burn firmware
