Some more news.... Humidity and Garlic

All nodes are upgraded with with humidity and  reading now with the accuracy of +- 5%. So, the deployed nodes have the following sensors

• Soil Temperature
• Air Temperature
• Air Humidity

Also, upgraded some of the nodes to solar in addition a new top cap was designed to accommodate this, see Figure 1.

Figure 1. Deployed node with solar panel, air temp, soil temp and humidity.

In other news..... I ran out of solder paste for the PCBs. I thought I had a another syringe of it but apparently I did not. So the PCBs have to wait until I get some solder paste in later this week.

Things are moving forward we actually found our first garlic growing above the mulch and up closer inspection we have around 25 ft poking through the mulch. Both the Susanville and Duganski garlic portions are active and doing well, see Figure 2. However, the real unknown is how well the shallots did.

Figure 2: Susanville garlic doing well.

Monitor Field Node Version 2

 Sensor Field Node 2 got an upgrade to Version 2. The upgrade is a pretty decent size one. It includes the following:

1. 3D printed enclosure
2. Second temperature sensor to measure ambient air temps 

Version 2 components disassembled on top. Version 3(yet to be deployed) on bottom.

Version 2 is on the top. Version 3 on the bottom. Notice Version 3's ambient temperature hood compared to Version 2.

Plenty of room in the electronics bay.

Version 2's ambient temperature probe. Version 3 has a hood that covers the probe but still allows exposure to ambient air.

Nodes deployed in the field. Node 2 is still the "old school" plastic ziploc container. It will be getting an upgrade to Version 3 this week

Node 1 Version 2 by itself

The Nodes in the field all by themselves

 The enclosure is further getting refined and a new "skinner" form factor is on the horizon that reduces the volume electronics bay. See the temps here:  http://colby.securecomo.com/
