Hi

I need to build a security system monitoring status of over 40 doors wirelessly.

The 6 story building have multi rooms require security system.

I was looking at Lora but someone said lora isn’t good for indoor application.

Any simple approach?

Thanks

Hello @spc6000 and welcome to the forum,

A nice and cheap solution would be using a ESP8266 or ESP32 which are Wi-Fi enabled wireless microcontrollers. I also suggest you look into the MQTT protocol.

Here are some papers/tutorials that you might find useful:
