Security for home is the prime necessity for any individual and this requirement can no way be compromised or ignored.
The articles explained under this category specializes in circuit diagrams designed for securing homes with advanced sensors and warning alarms.
A home can be vulnerable to many types of threats, it could be from human intrusion, animal intrusion, bugs, pests, or simply from the electrical wiring network which operate many of our sophisticated equipment.
The following list of articles cover the entire range so that the constructor can implement and able to provide a total 360 degree protection for his or her home.
The units are designed to work with advanced sensors which include IR and passive infrared detectors, trip wire alarms, microprocessors controlled alarms and sensors.
For safeguarding from mains hazards we have posts explaining high and low cut off circuits, surge protectors, and other similar concepts specially programmed for handling home wiring networks
In this post we are going to explore the datasheet of PIR or Pyroelectric Infrared Radial Sensor HC-SR501. We will understand for what purpose PIR sensor is used? Its basic trigger operations, pin connection details, technical specifications and finally we will be looking at some real life applications. We will begin by understanding the actual … Read morePIR Sensor Datasheet, Pinout Specifications, Working
In this post we will learn about a simple mechanism, and a circuit which will enable a patient’s IV drip bottle system to sound an alarm whenever it gets almost empty, and needs a replacement. The warning circuit will help doctors and the concerned employees to concentrate on other important matters while the drip systems … Read morePatient Drip Empty Warning Indicator Circuit
