[Avi Gupta] recently sent in their LoRaSense RGB Pi HAT project. This “HAT” (Hardware Attached to Top) is for any Raspberry Pi with 40-pin header. The core of the build is the custom printed circuit board which houses the components and interconnects. The components include an SHT31 temperature and humidity sensor, an SX1278 LoRa module, and a 10 amp 220 VAC relay. The interconnects include support for UART, I2C, SPI, and WS2812B RGB LED interfaces as well as a stackable header for daisy chaining HATs.
The attached components in combination support a wide range of use cases. Possible uses for this Raspberry Pi HAT include smart home systems, agricultural projects, industrial monitoring, smart greenhouse, remote weather stations, or alerting systems. You can detect weather conditions, send and receive information, switch mains powered loads, and use RGB LEDs for status and alerting.
If you’re interested in LoRa technology be sure to read about the Yagi antenna that sends LoRa signals farther.
And 1 Hz because….?
… it has LEDs to blink.

Is this the new quality/style of HaD? The project is clearly an ad for a commercial product (see datasheet). The article is a poor summary of a “project” with no content to reproduce it. Just an aggregation of buzz words like “HAT”, “LoRa”, WS2812B”,…
That’s not what I am used to read at HaD and that’s not why I visit HaD!
@Elliot Williams: Please comment!
Yeah, this one’s kinda lame. Sorry about that.
Then why keep the article? Delete it or at least make it disappear unless acessed directly by the URL.
Who wastes $100 on a Pi to put such a limited use hat on it and make it a remote sensor/switch?
We do those things with a $2 ESP32 now…
Not even a LoRa Gateway so what a waste of an rPi. No need to even waste the WiFi and Bluetooth of an ESP32 for this project when an Arduino Nano could do the trick.
