We need a standalone device developed which will have the following features/specifications
Features which must be there
1. Able to connect to Wifi &/or Bluetooth
2. Able to be solar powered (need to have built in Solar Panel & Battery if required)
3. After connecting to wifi/Bluetooth, should be able to read the data
4. The data will be on two parameters
5. First parameter will be true/false
6. Second parameter will be a 3 digit number
7. These parameters will be changing the state rapidly or at some intervals
8. The device needs to keep on displaying based on the relayed input from wifi/bluetooth
9. The display need to be somewhere similar to this. Assumed its LED display but open for anything which can be read from a distance and therefore, the digit size (Height) should be 3-4 inches.
If the first parameter is true then # should lit up if, its false then it should be off
123 represents the second parameter, which also can be changing from time to time. But will never exceed 3 digits.
1. If parameter 2 exceeds a specific predefined limit then the color of 123 needs to be changed from white to red. (As I have assumed LED, but open for changes)
2. I expect the size of this display should fit under 6x6 inches, small the better but can not go under 4x4 inches.
Order Size : Initial order will be around 1000 sets and within 3 months subsequent ordersize will be 10,000 sets each, depending on the cost.
