Design an Automatic Safe-Entry system that require little or no manpower to facilitate the Safe-Entry for all retail shops, offices, buildings, etc.

Most equipment in use for Safe-entry are convenience and require less manpower to operate. But the Team realized that it can be improved.

1. There are thermometer that is mounted on tripod but either it suits your height or you have to lower your head to get your temperature measured. If you are shorter than the tripod, like children. Ambassadors will need to use the handheld Thermometer. Why not make the thermometer height adjustable?

2. Different mode of check in, QR code for mobile app check in/out mounted on the queue poles or walls. QR code scanner for TraceTogether token and ID scanner for ID check in. We place all the check in and out into 1 location just after you get your temperature scanned.

3. Ambassador deployed at the Safe-Entry site to remind the public about maintaining safe distancing when checking in. We can use the available sensors to help them.

4. More often, we do not know the number of people restricted in the retails shop, especially during busy hours when the staff are busy with customers. Why not have a counter system that denies entry if the shop has reached the maximum capacity allowed?

The whole idea works similarly to a carpark gantry system. It has a counter to inform the driver of the number of lots available. If full, it will deny entry until someone scans out. Scanning the ERP in-vehicle unit upon entry and exit will be similar to temperature taking and checking in via Mobile apps / ID / token.

Code

SEAM (Main Code)Python

This code is programed to:

1. Set the total number of visitors allowed at any one time.

2. Adjust thermometer height to suit user.

3. Take Temperature of user

4. Check in via access card or QR code

SEAM (Sub Code) Python

The code is written to ensure the next person who is waiting behind the user who is checking in is maintaining 1m distancing. If it detects the person behind is less than 1 meter away, it will sound off with flashing LED and display warning.
