Beefed up Sensoring

A friend bought a couple of Sensirion SEN54s and I helped him get one working, and ended up buying the extra from him. It had been a few years since I researched what sensors were out there that worked well with Raspberry Pis, and were more on the industrial side than the hobbyist side. I was immediately enthused by Sensirion’s documentation, and their sensor looked top notch. My friend did all the homework on reading specs and comparing with others, it was really a no brainer.

With this SEN54 we’ve gained:

  • accurate humidity (the previous sensor was worthless)
  • VOC
  • PM1.0
  • PM2.5
  • PM4.0
  • PM10.0

It’ll be interesting to see the patterns. I’m honestly a little worried about what the particles will reveal seeing as we’re running 2 wood stoves in the house for half of the year. Reassuringly, the first few readings show we’re in the green, but then Nicole opened the stove to let out a bunch of grilled cheese sandwiches and the readings skyrocketed well above WHO guidelines for particles.

But those are only delicious cheese particles finding their way into your nostrils, surely that can’t have and adverse health effect. Jokes aside it’s interesting to see how much of a tail this benign event has. I’ll be really curious to discover more, I really have no idea what I’m looking at yet.

I am very glad to see the Pis become established as industry capable devices. It’s honestly remarkable what I’ve thrown at them over the years while they kept serving their purpose.

Buckets are Up

We upgraded the buckets significantly this year. The metal buckets were old, second hand, and I hear some old metal buckets might use a lead based solder. I don’t know if those do but the noxious idea is enough, they’re out. Maybe we’ll keep a few that look newer and in good shape. So microplastics it is! We tried aluminum buckets and they aren’t practical at all, but the few plastic ones we had worked well. Esther & I went to hang 50 of them in our usual tapping spots. Robin wasn’t able to hike this treacherous terrain with crutches, and he was very much bummed to miss out on the tapping action. It’s a big deal here.

The cat came with us, she too can tell Spring is around the corner.
