![]() A female USB A to male USB micro B adapter is also required for connection. The 3G dongle shows up as LAN adaptor ETH0 on the Pi with an address of 192.168.1.100 and gateway address of 192.168.1.1. I purchased the Raspberry Pi Zero W from, the W comes with no pin headers so I had so solder some on, the WH model however comes with them pre-soldered.įor the 3G dongle I’m using an old Huawei e3131, this dongle can be configured for the necessary network APN settings using a windows PC and then transferred to the PI Zero as plug and play with no need for any more configuration. These can easily be replaced with the RFM95 LoRa radios with only minor software changes. I’m only using the NRF24 radio as I had some spare here along with some old sensors from previous projects. In order to monitor sensors a long way from the main farm I’ve built a remote sensor gateway using a Raspberry Pi Zero, an old 3G dongle and an NRF24 radio. ![]()
