Raspberry Pi Wireless Door Sensor

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.

Raspberry pi wireless door sensor.

Sunfounder raspberry pi 3 model b 37 modules sensor kit v2 0 for rpi 4b 3 b 2b a zero raspberry pi board included 4 4 out of 5 stars 141 135 99 135. 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. Raspberry pi zero wireless.

Hooking up the sensor. When the magnet is less than 13mm 0 5 away the reed switch closes. They re often used to detect when a door or drawer is open which is why they have mounting tabs and screws. The ds18b20 and ds18s20 represents a very simple sensor.

The other half is a magnet. Compatible with raspberry pi a b a b pi 2 pi 3 pi 4 and pi zero wh models. These raspberry pi sensors are addressed via the so called 1 wire bus. However these modules can not measure additional information such as humidity and or air pressure.

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. Build a raspberry pi door window sensor with reed relais. Start up the raspberry pi and go to the desktop type. Normally the reed is open no connection between the two wires.

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. 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. Build a wireless door sensor with push notifications without programming or soldering. An advantage is that many different 1 wire components can be connected in series and read out by a single gpio.

This sensor is essentially a reed switch encased in an abs plastic shell. A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated.
