This project is a home monotoring system that will be able to detect temp data, VOC, and other data from the enviorment where it is placed. This data will then be used to detect wether smoking is present in the home and notify the user using a app built on react native.
Hardware Componets
- SPH0645LM4H (Sound Detection)
- ENS160 (Air Quality VOC)
- AHT21 (Temp and Humidity)
- RCWL-0516 (Motion)
Sensor Outputs
- SPH0645LM4H outputs Decibles to DB
- ENS160 Outputs VOC, AQI, eCO2
- AHT21 Outputs Temp, Humidity
- RCWL-0516 To be implimented
Hardware sensors are connected to ESP32 over i2c on gpio 21 and gpio 22
