The Arduino MySensors library makes it possible to create connected objects (IoT) and to make them communicate by radio waves. The library is responsible for creating a network of sensors and actuators that communicate with each other. MySensors supports 2.4GHz (nRF24L01) and 915mHz (RFM69) radio frequencies. The main home automation servers natively support the protocol. It is very easy to manufacture your own probes (temperature, humidity, air pollution, water leak detection, barometer …) and integrate them into Domoticz, Jeedom, OpenHAB, Home Assistant, just to name a few. the main ones. It is also very easy to use sensors and actuators from Node-RED. To operate and communicate with another software, gateway or gateway (network or serial) and necessary. Since version 2, it is possible to build a WiFi Gateway using an ESP8266 module.

nRF24L01 module with antenna engraved on the PCB

Project in interior or short distance (100m in free field).

nRF24L01+PA+LNA module with 2dBi external antenna

This module has an SMA connector for using an external antenna. In general, the modules are delivered with a 2dBi antenna to reach 1000m in free field (really free!). The slightest vegetable greatly diminishes the signal. If the environment is very difficult, consider buying a 6dBi antenna or 15 dBi.

Adapter with regulated power supply

Facilitates assembly, avoids connection losses (error! TSM: FAILURE). Compatible with all models of nRF24L01.
