and for who have the possibility, to characterize it to obtain a more or less precise value of the lux. I've remembered that wandering around my lab there is an old FPT100, so i decided to connect this analog device to the ESP8266 10bit ADC (Pin A0). This is the simple...
RTDs: WHAT'S IMPORTANT A typical PT100 RTD (see Figure 5) resis- tance varies less than 0.04Ω per tenth of 1°C corresponding to a signal level of 4µV at 100µA current excita- tion. Low ADC offset and noise are critical for accurate measurements. The measurement is ratiometric ...
