Micropython's NTC thermistor driver, assuming the nominal value of the NTC is 10K, is pulled up to vcc through a 10K resistor R1, and the temperature is calculated after ADC sampling.The default B val
If I use a battery to power a DCDC circuit, how can I be sure that the battery has enough power?
No matter how I think about this question, it seems contradictory. Is there any difference between usin
The circuit design is relatively simple, mainly including power supply, serial port screen, running light, DHT11, 485 and PM2.5 modules. 485 is used to read wind speed and direction data. The onboard
