see this link https://www.edaboard.com/threads/272349/

#define MOTOR PORTB.0

unsigned int adc_val;
unsigned int prev_state;

if(adc_val < 60) {

	MOTOR = 1;
	prev_state = 1;
}
else if(adc_val > 75) {
	
	MOTOR = 0;
	prev_state = 0;

}
else if((adc_val >= 60) && (adc_val <=75)) {
	MOTOR = prev_state;

}

What are 60 and 75? Are they relative humidity? Which moisture sensor are you using?
