Hi all,
I was wondering if there is a way to calibrate the MAX6675 ? I have two and both of them seem to off by 20 degrees.. Possibly this is the best accuracy I can expect, not sure I have never used them before..
I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system.
So please, can we have a 'how to' step-by-step guide to OTA? Please?

There are air quality monitors that can detect VOCs (volatile organic compounds), and some that claim to pick up marijuana smoke specifically. Devices like the Airthings Wave Plus, uHoo Air Sensor, or Plume Labs Flow could help identify changes in air quality. Another option is checking with industrial-grade smoke detection companies that provide sensors for businesses and schools, and some of them may also have solutions suited for home use.
If you want more information on vape-related products, including how they work and their components, check out Geek Bar Pulse X Platinum Edition. Understanding vape devices can help recognize patterns of use or detect scents earlier.

I will go with a Li-Po Battery type: 304048 3.7V 1200mAh
Might work, but maybe the internal protection will trigger with the high current peaks. I'd suggest you plan a 0 Ohm, (2512/THT) resistor as R2 and then replace it with a 100Ohm/1Watt if the protection triggers.
