The SmartProbe—A Moisture/Temperature Alarm

The well-designed SmartProbe is a low-cost device that monitors soil moisture, temperature, and light levels for potted plants. An audible alarm sounds when any measurement exceeds or falls below the preset limits. The battery-powered system also sounds the alarm when the power source is low. The R8C/13-based SmartProbe is an effective tool for any gardener.
