Beefed up pro mini with Mega2560

I was wondering if this could be an option for nodes that are running low on power/memory. Does anybody know if it is too power hungry compared to a regular pro mini?

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? S.

@wrendral said in "Remote Irrigation with LoRaWAN: LM27313 Challenges and PCB Design": 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.

@Tmaster Never assume the original PCB was just a circuit of components, the PCB can incorporate RF shields and antenna radio ground planes...

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.
