    • Temperature sensor + Switch sketch trouble

      I have a board setup with a switch and a temperature sensor. When I try to combine the two sketches I get multiple errors.
      Can someone take a quick look at combining the two sketches?

      I believe the big black cylinder is an inducer to make the siren pitch go up and down without completely dropping out. If you look above the black blob and under the cylinder there is an extra through hole which is perfect for triggering. FYI I bought these from Dollar tree. Ill try and see if I can take a few pictures or a video of it in action.

      Each one of these little sirens produce a ear piercing sound, enough that it hurts your ears, I hooked one up to an arduino and triggered it with a simple on off sketch. Figuring out the broadcast would be the next part.

    • RE: 2 AA batteries with step up converter to Vcc pin VS 3 AA batteries to RAW pin

      Does anyone have the spec sheet for the Chinese step up regulator? I bought a few of these to test

      It uses a magnet to know when the reed switch is set off to complete the circuit, I was buying them to use the reed switches for door sensors which waiting for a shipment from China.

      I but them from my local $1 store, but I was able to find some that look the same on amazon.

      It is a simple circuit with a reed sensor to trip the alarm.

      give me a second to upload a picture of one open.

      Why not hook up a window siren alarm to the arduino? They are extremely loud, and only cost $1. That combined with some LEDS on every sensor node would work wonders. 10+ alarms all around the house with blinking lights should stop someone.

    • RE: The new ESP8266 WIFI models

      I have a few of these waiting to be exploited 🙂 Wireless gateway was my same thought. They use alot of power, up to 3x that of the RF24 module so I do not think they would be ideal for battery powered sensors.
