It depends on how many samples of visibility sensor you require and whether we have some in stock. If we have some in stock, we can offer one or two samples for free. And if we are out of stock or your required sample needs to be customized, we are afraid that we can not offer the sample free of charge. But the sample fee can be refunded once you place the order.
