door sensor operations: unveiling their functionality
Door sensors, those inconspicuous yet indispensable devices, play a pivotal role in modern security, automation, and access control systems. Their functionality relies on a diverse array of technologies, each tailored to specific applications. Magnetic reed sensors, for example, employ the interaction of magnets and reed switches to detect shifts in magnetic fields when doors open or close.
reed door sensor (battery powered esp32 with esphome(yaml))
Hi Folks! I just finished my door sensor with esphome and some cheap reed sensors. Total cost for this project is about 15 €. I’m using a WEMOS LOLIN32 ESP32 running on a 18650 Battery soldered to a strip board. Positive output is connected with an ADC Pin (34) and the reed sensor itself is connected with +3V and Pin 14 . Pin 14 is defined as a binary GPIO sensor and also as the wakeup pin ...
build a raspberry pi door / window sensor with reed relais
This will allow you to query if a window/door is opened or not. If you want to wait for the state to change, you can use the following function: Python. 1. GPIO.add_event_detect(MAGNET_GPIO, GPIO.BOTH, callback=my_callback) In this case, a function called my_callback() must be present, which is then called.

Go to Tools > Board and select your ESP32 board. Then, go to Tools > Port and select the COM port the ESP32 is connected to. Open the Serial Monitor at a baud rate of 115200 to check if the changes are detected. For prototyping/testing, you can apply the magnetic reed switch to your door using Velcro.
esp8266 nodemcu door status monitor with email notifications (ifttt)
First, you need to include the ESP8266WiFi library so that the ESP8266 can connect to your network to communicate with the IFTTT services. #include <ESP8266WiFi.h>. Set the GPIOs for the reed switch and LED (the on-board LED is GPIO 2). We’ll light up the on-board LED when the door is open.
a list of door sensor / reed sensor hacks! (aqara, xiaomi, others)
There’s so many cool little door sensor hacks floating around that I thought it might be useful to have a meta thread? Like this one.. I really like the Aqara ones, which are small, cheap, and reliable in my experience. I’ll add the one’s I know about, and add one I’m just playing with.

a guide to the applications of hall effect and reed switch sensors
When the door closes, the sensor detects the proper magnetic field and the LED turns off. In this application, a microcontroller within the appliance obtains the signal from the reed sensor and then the control unit activates or deactivates the LED.
