In Progress

Build a working prototype "Air Quality Device with WiFi" talking to cloud service

We prefer someone who is located in China and speaks Chinese, this will be better since sourcing parts and talking with our service/WiFi provider who talk Chinese will be easier.

We are looking to manufacture a prototype Air Quality device with WiFi connectivity, that will do the following(More details in the attached wordfile):

1: Read temperature and humidity

2: TVOC sensor that will show air quality and CO2 reading.

3: Short distant motion sensor in front of the device. If you move your hand close in front of the device, it will light a LED. If the air quality is good (TVOC sensor +CO2) then it will light up shortly green, if its average quality it will light up orange color. If its bad it will light up red.

4: Device will show air quality indicating true led color, even if its not connected to the WiFi

5: Regular 3x AA batteries, this will be the power source for the device

The data from these sensors are sent to the SoC (Wifi Chip) that will take the incoming sensor data and send this to our cloud solution that communicates this data to our Phone App. The app will then show this data to the user. We currently have a working app for heaters, we will just add support for this new device. Our other products are using similar WiFi chips and the Able Cloud solution provider.

Key point: Cost needs to keep price as low as possible and power consumption needs to be kept at a minimum since the device will be powered by battery (3xAA batteries) Our aim is to have at least 12 months battery time. We are open to other/better batteries if it helps
