Yes, there are several ways to do that.
The problem is the sensor gets saturated after a while. You can bake the moisture out in the oven, on 50 degrees centigrade for about 15 minutes, is you have an oven that regulates its temperature well.
You can also swap the sensor at De WAR and then we will bake a whole batch at a time and measure which ones are good enough to be out in the field again.
