Hi everyone,
Very new to all this, very new, not even enough knowledge to be dangerous at this point, first few steps along a very long road...... and have a question relating to a small PIR sensor that i have, they are designed for Arduino i think and rated at a working voltage range C 4.5-20V, which is fine as i'll be using a 12V battery to run it, but the Level output is High 3.3 V /Low 0V, so am i right to think that input is 12V but it will only supply 3.3V to whatever circuit that its a part off ?
It will run in my garage to turn some LED lights on when i'm in there pottering about and to turn them off when there is no activity, i use 12V PIR sensors outside like these that are purpose built for what i want but they are very bulky and these small PIR sensors are very discreet and i have them for some reason, not sure why.....
the datasheet for these are attached, could someone have a look and see if they are fit for purpose ? or should i get some other PIR like these one's ?
Many Thanks
Shaune.
