I connected one soil probe to power, and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and photoresistor, but connected those to ...

Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from Microchip Technology Inc. The chip comprises an analog temperature sensor that converts temperature to analog ...

I built a program about a month ago for ESP8266-01 to read the value of a NTC, LDR, potentiometer or similar. I published the code on a local Arduino forum in Facebook. Remember that this device ...
