Hello, I’m making a project that will log as much data possible of what is around it with an atmega328 + sensors.
So far, the sensors I got are:
-Temperature and Humidity module
-GPS module that provides coordinates and some other interesting stuff
-PIR Motion Sensor module
-A knock sensor
-Barometric pressure sensor
-An external voltage reference to monitor the battery voltage
What I’d like to add later on:
-A decibel (dB) sound level
-MQ-x Gas sensors. ← current issue, they consume a lot of power because they have to warm up.
-Wifi and Bluetooth modules
-IR Receiver and Transmitter
All this data gets logged it a SD card.
Keep in mind that all this is also being powered by batteries, therefore, I cannot have something that eats up a lot of power.
This will not be constantly powered on. It will be turning on for example once an hour, hopefully for a period under a minute and then it sleeps. After a day or so, I should be able to graph the collected data.
The objective is to record into an SD card everything of what is going on around it. Also, this is an indoor project.
What other sensors could I apply to this?
