Ultimately, of course, the solution is to fix the sensor/microprocessor. This is an intermittent problem that has affected at least 2 different sensors. Since it is a bit slip, it likely is an issue communicating between the PIC and the SHT. Thus, it appears that either the PIC, SHT, or the interface circuit is marginal in some aspect. Is the timing too fast? Is a pull-up resistor needed? Is some timing wait state needed?
