With TechGrows Seconds interval Timer you can adjust your interval timings to the second for example to control a waterpump. It can be adjusted from 1 to 360 seconds and from 1 to 360 minutes. It lets you adjust intervals like 120seconds/100minutes or else easily. Also the Seconds interval Timer has the option to work only when the built in light sensor is detecting daylight. In this case the light sensor is turning the timer off when no light is detected.
