Electronics Project
Working on a electronics project for work which required some soldering. Not super great at it, but I've never had much opportunity to work at it either. I ordered these ADCs (Analogue Digital Converters) to measure DC input voltage from our network sites (which have a range of potential of various configurations) and stepping the voltage down to 3.3v for this little board to be read by the I2C bus on a Raspberry Pi.
This is just one piece in the sensor project, as I have built out "cabinet monitors" to read temperature, humidity, DC input voltage, AC power status and door open status. The Raspberry Pi is running some self composed python code to perform HTTP REST APIs to POST the data to our API server.
Zabbix is querying the API server and retrieving the data that the Cabinet Monitor POSTed to the server and graphs it quite nicely to watch voltage, temperature and the rest. We can also set Trigger alerts in Zabbix to get instant notification when a door was opened or when the power went out & we're running on battery power.
I'll post some pictures of the cabinet monitor sometime...
