I have a prototype fro IoT monitoring. The purpose is to count the number of people who sitting on the chairs.
The chair will be install sensor (infra red or dry contact), connected to ESP8266, the via wifi connected to NodeRed whoihc installed on Raspberry Pi 4.
So every time there is a person sitting on the chairs then sensor will detect and send to ESP8266. ESP8266 then send info/message to Node Red.
I need some one to do job coding for NodeRed to receive message from ESP8266. Then NodeRed will store the counting information from ESP8266 into it's database and people can see the number of people sitting on the chairs. The number of chairs will be between 4-8. So people can see how many each chair every day.
The block diagram of the project as attach.
That's the objective.
