It may be so convenience if you can know the only one restroom in office is occupied or not. There is a human detect sensor like PaPIRsVZ EKMC1601111. We create a html program which is like a lavatory signal (such as in airplane) by using this sensor.
Materials
- obniz x1
- power supply for obniz x1
- PaPIRsVZ EKMC1601111(pyroelectric infrared sensor) x1
- PC to open HTML file x1
Steps
Step 1
Connect PaPIRsVZ EKMC1601111 to an obniz. Wire them like the table and the image below.
obniz | PaPIRsVZ |
---|---|
0 | GND |
1 | signal |
2 | Vdd |
Step 2
Then, put this on toilet. When that’s done, let’s open HTML file to know the restroom is occupied or not!
