temp control

[Marco3231st]

this issue is made to figure out how to control the smoke of the smoker

[Marco3231st]

we could look at the power output of the heat element with different voltages, see which one fits the best with our smoking needs and put a fuse with the corresponding amp so that it doesn't go higher.

We want our temperature to be under 500 but over 300 degrees.

Unfortunatly the temperature sensors are to weak...

We could use this thermo-couple https://www.amazon.ca/Twidec-NPT-100-temp%C3%A9rature-Thermocouple/dp/B07QN33FFB/ref=sxin_17_pa_sp_search_thematic_sspa?__mk_fr_CA=%C3%85M%C3%85%C5%BD%C3%95%C3%91&content-id=amzn1.sym.1c956678-8ce3-4ff6-a3fd-b942e56a71ae%3Aamzn1.sym.1c956678-8ce3-4ff6-a3fd-b942e56a71ae&crid=XAGIP3USFFOR&cv_ct_cx=high%2Btemperature%2Bsensor&keywords=high%2Btemperature%2Bsensor&pd_rd_i=B07QN33FFB&pd_rd_r=0dc53e85-d45d-48aa-96ab-bb730904cfd1&pd_rd_w=eyW15&pd_rd_wg=dyTPG&pf_rd_p=1c956678-8ce3-4ff6-a3fd-b942e56a71ae&pf_rd_r=3WD498E9P81FG9K75QDK&qid=1690215459&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sprefix=high%2Btemperature%2Bsensor%2Caps%2C138&sr=1-4-acb80629-ce74-4cc5-9423-11e8801573fb-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9zZWFyY2hfdGhlbWF0aWM&th=1

with this module, we could easily control the temperature
