Hello everyone
I want to use a Humidity Resistive Sensor that needs AC voltage to prevent polarization of the sensor; the result is converted and rectified to a DC voltage
After research on oscillators used only transistors I find a lot of examples (sincerely I can’t imagine how can you know them all, this is beyond my capacity) and since I am beginner I can’t choose the simplest one that can give me good AC signal
I know “good” and “simple” can’t be together all the time, but I you can the best from simplest oscillators (few components: two or three transistors and three or four moderate capacitors)
Please help me to:
A simple oscillator who gives a good AC signal ranges from 30 Hz to 3 kHz
Can I use this simple oscillator to toggle to 1/10 Hz or less to use is for my a timer in the same time as a Humidity Resistive Sensor
Thank you very much and have a good day.
