I do this with a simple hall effect and an arduino leonardo/dragino
shield board which allows me to also watch battery on the generator and
charger output.
I monitor temp in generator room and Co2 levels which will activate an
exhaust Fan at certain levels. The other room is where all the radio and
data gear is I have another
that monitors the doors the lights and temp as well. I am trying to get
it so I can just replace the thermostat and turn on the AC when needed.
So much fun with transducers and comparitor circuits to get optimal
sampling from the sensor and feed the mean into the arduino so it doesnt
get false positives.
I have been asked by the boss about doing a biometric lock on the doors
at a couple sites which I think can be done and integrate to what we
have already.
I only have the 2 large sites that require alot of attention but not so
much cuz most is automated to the point we get emails when something
isnt right.

Some are. Others are hall effect sensors which need 5v and output a
voltage.
I've had some customers hook up the output of these to a voltmeter or
shunt input with reasonable results. What I've had in the queue is a
module set up specifically for these sensors and which reports percent
directly.

Holy cow, it looks like I should get around to finishing up the
$59+sensor ($50ish) add-on module for the sitemonitor system....
Didn't realize these were so expensive.

Generac 7005 Propane Tank (LP) Fuel Level Monitor - WiFi
enabled
https://www.amazon.com/dp/B072KJBLV2/ref=cm_sw_r_cp_api_i_cqtsCbZ22K84X
The only down side is it has to connect to a 2.4ghz SSID with
no security enabled. So we engineered the WiFi AP to only
accept that MAC address and only hand out 1 ip to that device
and then fire walled everything so the monitor could only
talk to their cloud. Basically the device has a battery in
it and it turns on once a day for a minute and pushes its
data to the cloud so you can access it on their free AP or
website.

What solutions exist to monitor propane tank levels
remotely? I've got an off-grid site with three 100 gallon
tanks. The propane guy setup the manifold such that the
tanks should drain sequentially, but I'd like to
monitoring/chart them remotely. Each tank has a R3D
gauge, but not sure what sensor to plug into them.
