AUTO ON/OFF TIMER
Widely used to switch ON/OFF devices with settable timing from 3 to 30min
This is a simple and inexpensive timer, widely used to switch on/off devices. It has a settable timing between 3min to 30min. The circuit is build around counter IC4060 (IC1) and inverter IC4049 (IC2).
The circuit switches on autometically when power is on, and it switches off when the settable time is over.
COOLER TIMER
Timer with ON time and OFF time setting for cooler/pump.
During summer seasons, we all us knows the need of coolers. If cooler is on for long time, then the requirement of water is also very large. To minimize this problem to a large extent cooler timer is designed. This circuit control the on and off time of cooler water pump according to the user requirement. The minimum and maximum time setting are fraction of second and one-and-a-half minute respectively.
