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.
@OldSurferDude Thanks!
I didn't touch the Arduino IDE for a while and forgot that the MYSBootloader doesn't come included in the Mysensor's library... My bad.
Thanks for the link! I should had searched first...
I use the OTA feature since 2017... It works well. So well that I forgot how to load the bootloader...
Regards!
Hello
I still didn't figure it out exactly, what is the issue with LGT8F328P and arduino, but for start, it can work, if you define 4x faster baud rate. So I define MY_BAUD_RATE 76800 and connect terminal with 19200, and it works. LGT is started in 8 MHz by default, and it looks like this is not corrected with mysensors. But this only helped for serial port, because later I had issues with DHT library timings.
If I later change speed to 16 MHz and start serial port again, it works as expected:
noInterrupts();
CLKPR = 0x80;
CLKPR = 0x01;
interrupts();
Serial.begin(19200);
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.
as I experienced, MQ sensors are not really gaz sensitive, they are more particle size sensitive when hot enough and when not totally scrap.
I would not rely my life on them, if you have an alcool spray use it around and any MQ will to go the sky...
