Bluetooth door sensor raspberry pi.
There are many use cases continue reading how to make raspberry pi bluetooth proximity monitor.
Read now we can try reading the output from the pir motion sensor.
The other half is a magnet.
Unlike many projects using this hardware we use ipv6 sub ghz 6lowpan communication instead of bluetooth.
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.
The sensor outputs a digital high 5v signal when it detects a person.
A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated.
The ds18b20 and ds18s20 represents a very simple sensor.
We use the sensortag hardware with sub ghz configuration.
The door sensor consists of one sensortag and one ordinary magnet.
The project also lets users send a command to the door thus enabling you to.
These raspberry pi sensors are addressed via the so called 1 wire bus.
Start up the raspberry pi and go to the desktop type.
Get it as soon as fri sep 25.
Normally the reed is open no connection between the two wires.
An advantage is that many different 1 wire components can be connected in series and read out by a single gpio.
