After ADC conversion result is stored into 16-bit ADC_DR data register (remember that conversion result is 12-bit), then End of Conversion (EOC) flag is set Oct 20, 2018 · Temp= 38. 英語版の最新版  27 Aug 2019 As any measurement instrument you want to be accurate, also the temperature sensor needs to be calibrated regularly. 7 mA current consumption Operating temperature: −40°C to +125°C 16-lead TSSOP package Oct 10, 2019 · where a higher degree of accuracy is required, you may wish to re-calibrate the sensor yourself. Here is the full sketch: #include <EEPROM. +50°C for both Ta and To) * High (medical) accuracy calibration * Measurement resolution of 0. STM32 will control stepper 4) The sensor should not be installed in the air flow way of the air cleaner or should be shielded by some structure. info) Dissolved oxygen sensor is the key of dissolved oxygen measurement and it is usually implemented by electrochemical method, which measures dissolved oxygen content by the diffusion rate of molecular oxygen through film. A target seems clear but when I try to download source code to flash, it doesn't send any data to COM port. stm32 temperature sensor calibration
