Hi, I'm quite new to Raspberry world.
Instead of buying another surveillance low-cost cam, that I expect to works for few weeks, -with an insufficient software-, I dream to assemble a kit based on ZeroW board.

IR-cut lens are available, but I would use a dedicated 12V IR led illuminator (25m distance), to be activated by a light sensor.
Not believing in motion detection techniques based on differences between captured images, I foresee a PIR sensor that should activate:
notice on Telegram, save picture on cloud, send a mail (with attached picture).

I found some hints on the web about the available software, but now I'm anxious about the shopping list:
A) case (no waterproof required) with the possibility of wall mounting
B) sensors (PIR, light)
C) relays to activate IR led illuminator
apart I'm assembling a dedicated UPS (220V to 12V, converting one output to usb 5V for PI).

any suggestion?
Thks Alessandro

maybe my question was too ambitious, or unclear.
just to split the project into steps.
Step 0: I completed a DIY UPS, with 5V usb output dedicated to PI, and a 12V output for accessories.
Step 1: I'm looking for a solution to pilot a IR led (12V) according to a light sensor.
Which board / sensors combination is a better choice? in term of programming first, then reliability and cost.
Step 1 bis: the same board (relay based, I imagine) could manage also a PIR sensor?

next steps will be important too, but now I need the shopping list for my PI zero W step 1.

any suggestion, hint or link to already developed -similar- projects are welcome!

Sorry, I'm a little confused as to what you are asking. You seem to list the items you need then are asking what items you need?

Have you had a look through our shop? https://www.modmypi.com/shop

thanks Dave,
as I'm new to PI world, I know the elements of my projects, but when I find on this shop many choices for the same sensor, then I need help!
many sensors require breadboard, I would prefer a universal card, as Dexter ( https://www.modmypi.com/raspberry-pi/br ... rch=dexter), where many sensors could be arranged simply plugging into. these are different approaches, with pros & cons.
for a newbie, it could be easier breadboard or the other card?
lux meter: again, a solution where the target value can be set up by the user, is better for me.

my basic question is to buy sensors that are compatible and easy to assemble (and to develope the code)

The GrovePi is certainly a good easy place to start - https://www.modmypi.com/raspberry-pi/br ... es/grovepi

There are loads of sensors compatible with the GrovePi which can be found here - https://www.modmypi.com/electronics/grove
