Stable battery PIR Sensor
I am busy building an burglar alarm for my home.
Because of this its important its a wireless system (to not go down during electrical failure in the house).
I wonder is there any stable good PIR sensor that works with battery?
I have sourced the forum but not really found anything. I have a couple of Sensebender micro boads lying around that I would prefer to use for this.
Its off course also important that there is no false triggers, because then it would be a very unreliable system.
http://forum.mysensors.org/topic/1088/battery-powered-pir and http://forum.mysensors.org/topic/2715/slim-node-as-a-mini-2aa-battery-pir-motion-sensor are battery powered pir sensors.
Here is the open hardware for the slim node.:
I've been away from home two weeks now and my two Slim Node Mini PIRs have delivered heartbeat messages every second day and no false trig.
Maybe I will try this design then. But I dont need them so small so will probably use the bigger PIR sensor in mine.
I will revert when I'm done
@m26872 Hello, have you not used any voltage regultator for the pir sensor? You just give it direct connection to the batterypack?
@Fredrik-Carlsson Yes, for power economy (efficiency and dropout voltage). Whole node worked at 1.6V, as stable as before.
I think you should read about other PIR setups as well, I haven't yet tried the standard sized one myself.
I will try tomorrow to do it without any voltage regulators together with a sensebender micro. I have the bigger pir sensor though, but I dont think its much difference on thoose. We will see.
