Submersible Timer Circuit with Pause Feature during Mains Failures
The post explains a submersible pump timer circuit programmed to cycle at 60 minute interval for watering the fields consistently. It also includes a time “memory” feature which ensures that the timer “remembers” the counting during mains failures, and restarts exactly from where it was interrupted when mains power is restored. The idea was requested Read More
Automatic Food Warmer Lamp Timer Circuit for Hotels and Restaurants
The post discusses a simple food warmer lamp timer circuit for restaurants and hotels which can be used for automatically switching OFF the lamps after a predetermined time whenever the food under the lamps are idle or in the absence of an interaction under the lamps, thus saving precious electricity. The idea was requested by Read More
