Input voltage range is 220V AC derived voltage by the transformer into a voltage 12V. 12V AC voltage is passed to a rectifier circuit that produces a DC voltage. DC voltage is then filtered by capacitor C1. In normal circumstances, if the circuit is connected to the [...]]]> http://circuitdiagram-schematic.com/1097/simple-ups-circuit-diagram/feed/ 0 http://circuitdiagram-schematic.com/1065/simple-car-parking-sensors-circuit/ http://circuitdiagram-schematic.com/1065/simple-car-parking-sensors-circuit/#comments Thu, 06 Oct 2011 12:36:57 +0000 admin http://circuitdiagram-schematic.com/?p=1065 This circuit is a car parking sensor, circuit takes advantage of the photodiode as the sensor distance. The distance between adjacent sensors should be about 2 cm in the same direction. The workings of this circuit is to detect the distance between the rear bumper cars with objects behind the car, making it easier for [...]]]> http://circuitdiagram-schematic.com/1065/simple-car-parking-sensors-circuit/feed/ 0 http://circuitdiagram-schematic.com/1023/simple-automatic-air-flow-detector-circuit-and-circuit-board/ http://circuitdiagram-schematic.com/1023/simple-automatic-air-flow-detector-circuit-and-circuit-board/#comments Wed, 07 Sep 2011 06:07:42 +0000 admin http://circuitdiagram-schematic.com/?p=1023 This circuit is a simple detection of air flow, this circuit can be signaled in the event of air flow. The sensor used is a filament incandescent lamps. These sensors will experience changes in heat if exposed to the wind. If there is no air flow, the filament resistance will be low.
