This is the LoRa 9x @ 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings.

Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth Low Energy!) but what if you want to send data very far? Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.'

An AC Dimmer is used to control the AC cycle. Normally, a dimmer is used to turning the power ON/OFF for lamps or heating elements, it can also be used in fans, pumps, air cleaners, etc. Makerfabs Lora AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC. Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay is implemented to make the AC totally On/Off. On-board AC/DC module implemented, so no external power supply needed, suitable for field applications.
