I took baby out for a 5 minute walk, it’s first, to take humidity and temperature readings and radio them back to a server. We visited a bedroom and the greenhouse. It was all so very new.<\/p>\n\n\n\n

I’m building a solar powered radio humidity & temperature reporting unit; I plan to have three of them, two in the greenhouse and one outside. The unit consists of two circuit boards, a battery, an all-weather temperature probe, and a solar panel. The unit send Lora radio packets to a receiver in Peck Cottage every 10 seconds providing the last 10 readings for each second.

Why, John, you may ask? With the 1,000 psi fogger unit, I want to measure its effectiveness and gauge when I should have it activated and for how long. Having data in small intervals will help me evaluate and determine when the fogger should be activated.<\/p>\n\n\n\n

After spending several days getting a ChirpStack server running on an old RAK unit that is connected to a Raspberry Pi 4B computer, I finally got the probe to send via radio [Lora] to the RAK it’s payload of humidity and temperature data. <\/p>\n\n\n\n

Here’s a screenshot of the ChirpStack server showing the incoming packets.<\/p>\n\n\n\n

And here is a peek at the data within it show 10 humidity and temperature readings for the last 10 seconds:<\/p>\n\n\n\n
