Wifi Door Sensor Raspberry Pi

Entry sensor monitors your door window server cabinet or catflap.

Wifi door sensor raspberry pi. Compatible with raspberry pi a b a b pi 2 pi 3 pi 4 and pi zero wh models. Thought i d do something a little different today and just show a demo in the video below and write out the steps to the actual project here and on github. Although the sensor is highly accurate 0 5 c accuracy you can calibrate the temperature reading using a configuration in the wifi sensor app. These raspberry pi sensors are addressed via the so called 1 wire bus.

Raspberry pi zero wireless. 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. Welcome to the 13th raspberry pi tutorial. An advantage is that many different 1 wire components can be connected in series and read out by a single gpio.

However these modules can not measure additional information such as humidity and or air pressure. A wifi access point advertises itself through an ssid and can be connected to via any device. The two left most terminals are to control the door. 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.

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. A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated. Hooking up the sensor. Low voltage labs traffic lights.

And the next two are the safety sensors which i left alone. Build a raspberry pi door window sensor with reed relais. The device supports dual wifi mode allowing it to be wifi access point and a wifi client at the same time. Start up the raspberry pi and go to the desktop type.

A raspberry pi with sd card and os installed i m using the pi 3 but any model with gpio headers will do unless you fancy some extra. Build a wireless door sensor with push notifications without programming or soldering. The ds18b20 and ds18s20 represents a very simple sensor. Gpio project kit for raspberry pi.

Raspberry pi sends an email to your phone when door is opened or closed logs the event to a text file.
