High-tech rain gauges
Gone are the days when you have to step outdoors during a drizzle or storm to check the rain gauge. Wireless remote gauges with indoor displays allow you to monitor rain while it's falling. The fancier models use self-emptying rain cups.
Besides recording daily rainfall amounts, some models store measurements in memory for at least a week. Other extra bells and whistles include indoor/outdoor temperature measurements and greater transmission ranges. Prices start at around $21 and go upwards of $100, depending on model and manufacturer. Check online or local hardware stores or online weather stores.
