electronic circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, immediately discontinue electrical flow....
Summing CT Measurements
This could be achieved by monitoring separate points either through the same recorder or, less ideally, two separate recorders. In both cases, the results need to be artificially summed to obtain the total current draw. Two problems arise: first, the...
AC/DC Microammeter Circuit
This is a variation of Mr. Marian's "Simple Micro Ampere Meter Circuit" that employs active circuitry and an analog meter to measure sensitive DC currents.
The circuit in question is designed to provide precise measurements of very low DC currents, often...
high side current measurements
It is often challenging to measure the current in the positive lead of a power supply, such as a battery charger. Fortunately, specialized integrated circuits (ICs) have been developed for this purpose in recent years, including the Burr-Brown INA138 and...
The alarm circuit diagram for safety box and other metal objects
When an individual touches the safety box or other protected metal objects, the sensor circuit generates a pulse to the alarm circuit. The positive edge of this pulse activates the semiconductor and thyristor flash GE, subsequently triggering the camera to...
Gate automatic lamp circuit
The circuit utilizes multiple integrated circuits to form an automatic lighting device that is activated by door and window sensors. It includes CD4093 digital integrated circuits, a relay, and a power supply circuit. The system typically remains closed when a...
Wire Break Sensor Alarm Circuit Schematic
The circuit of a loop sensor-based simple security alarm is described here. The sensor loop consists of a short length of thin enamelled copper wire.
The loop sensor security alarm operates on the principle of detecting interruptions in the circuit formed...
Current-shunt-amplifier
This circuit measures the power supply current of a circuit without using a current shunt resistor: R1 is only 3 cm of #20 gauge copper wire. A length of the power distribution wiring can be used for R1. The MAX420's...
Add a sensor to a board and measure something with it
This week's plan is to build a device that warns of the potential for a knockdown, which is the process by which an over-canvassed ship is laid over on her beam-ends. The risk of sinking is high during this event,...
