I'm using the ESP8266 Nodemcu V2, so the ADC (Pin A0) only gives me an output of between 0.00v and 1.00v. That affects the stray field capacitor. Now you can use any general purpose NPN transistor whose collector current is greater than 30ma. input[type="password"]:focus, This sensor mainly utilizes capacitance to gauge the water content of the soil (dielectric permittivity). This great difference allows this capacitive moisture measuring technology to get a high response regarding the water content of the measured materials (bulk solids). mt('send', 'pageview'); Home » dualpixel blog » capacitive soil moisture sensor working principle.
