Build a wireless door sensor with push notifications without programming or soldering.
Raspberry pi wireless door sensor.
An advantage is that many different 1 wire components can be connected in series and read out by a single gpio.
Playing with a raspberry pi low voltage labs traffic lights and an adafruit door sensor.
They re often used to detect when a door or drawer is open which is why they have mounting tabs and screws.
The door sensor has two wires connect 1 wire doesn t matter which to a free pin i chose pin 8 you need to refer to this pin in the code explicitly and the other to one of the ground gnd pins pin diagram here.
This sensor is essentially a reed switch encased in an abs plastic shell.
Today we set up a door sensor that sends a notification to your phone when the door is opened no matter where in the world you are.
Entry sensor monitors your door window server cabinet or catflap.
When the magnet is less than 13mm 0 5 away the reed switch closes.

The ds18b20 and ds18s20 represents a very simple sensor.
These raspberry pi sensors are addressed via the so called 1 wire bus.
Normally the reed is open no connection between the two wires.
A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated.
In addition to a surveillance camera and motion sensors information about open windows and doors is also of interest to a self built surveillance system.
Build a raspberry pi door window sensor with reed relais.
Raspberry pi sends an email to your phone when door is opened or closed logs the event to a text file.
Because we use the thingsquare system and off the shelf hardware we do not need to do any.
The other half is a magnet.
As delivered the door sensor comes with bare wires we could solder these directly to the gpio pins on the pi but for a more re usable solution it s better to use the jumper wires one end of the.
