I am working on a project for one of my subjects for which I need to connect different sensors (e.g., light, current, gas, optical, etc.) to a master arduino board wirelessly. Then based on the status of these sensors, the arduino switches on and off certain LEDs. Can someone help me with how I can …

Review this link. [image] Getting Started with ESP-NOW (ESP32 with Arduino IDE) | Random Nerd Tutorials Learn how ESP-NOW work to exchange data between ESP32 boards using Arduino IDE. ESP-NOW is a connectionless communication protocol developed by Espressif Systems. …

[image] arduino-2026: wirelessly. Little more precisely..? Could be IR, bluetooth, wifi, lora... and so on.

what is the distance between modules? do you have local WiFi coverage?

[image] arduino-2026: Can someone help me with how I can form these wireless connections between the sensors and the arduino? Begin by defining the message format and data that you will need to communicate the data from the sensors, including a code to identify which sensor the data is coming…

distance between the modules should be around 4-5 metres and we do have local wifi coverage

we're thinking wifi, but if that's too expensive to carry out then we'll look for a cheaper option.

[image] arduino-2026: we're thinking wifi you could use ESP32 micros (with onboard WiFi, bluetooth classic and BLE) cost about £7 on Ebay in UK - the ESP32 is supported by the Arduino IDE the master could run an Access Point remote ESP32's could send sensor data to it or look at ESP-NOW

[image] arduino-2026: distance between the modules should be around 4-5 metres and we do have local wifi You find esp8266 boards at $2 for wifi, so while IR could be one option for that distance, it's not worth the trouble. Setup is so simple, sensors connect to one Esp and master"LED" Esp r…
