Cellular Communication
The main goal for this is to have a hive sending data in areas not covered with network cable to house or outside WiFi range. There is also a problem with sites without AC power. This is also covered in the section for Solar Panel.
My setup for this is:
- Raspberry Pi
- HAT board
- Weighing cells
- 2 x DHT22 Temperatur / Humidity sensors
- TSL2591 Lux sensor
- Edimax E180 3G modem
- WiFi from Raspberry
There are several things to think about
- Is this the only hive to be connected to internet.
- If there is more that one, you need to set it up as a router.
- If there is only two hives a ethernet cable between would be the most power effeciant.
- If there is more than two, you need a ethernet hub or using wifi between hives (wifi use a lot of power)
1. Only one hive connecting
Connect USB modem to pi
Check that you can see the USB modem:
