Automatic Room light Control With Bi Directional Visitor Counter
The objective of this project is to create a controller-based model that counts the number of individuals entering a specific room and activates the lighting accordingly. This is achieved through the use of sensors that detect the current number of...
Timing circuit
Load current starts approximately 0 RC after the switch is thrown.
The statement indicates that the load current begins at approximately 0 ohms after a switch is activated. This scenario is common in electronic circuits where a switch controls the flow...
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...
Tracking Transmitter
This is a small battery-operated tracking transmitter that broadcasts a repeating radio signal detectable by a directional antenna. The transmitter emits an isotropic signal across the FM band, specifically between 87 to 108 MHz. An ordinary FM radio can be...
Agricultural harvester warehouse full schematic reminder
The circuit functions as a reminder system utilizing a photodetector amplifier circuit along with a sound and light alarm circuit, as illustrated in Figure 1. The photodetector amplifier circuit consists of a pilot light (HL1), a light switch (S1), a...
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...
Sensor-Activated Relay Pulser Circuit
A sensor activates transistor Q1 to turn on the low-frequency 555 oscillator, which generates pulses to control LAMP II. The sensor may respond to variations in light or temperature. Either resistor RA or RB can function as the sensor, depending...
Scoobas Solution Sensing Tactic
This document serves multiple purposes, primarily to document the methods employed by a Scooba robot to detect: a) the presence of an acceptable cleaning solution being delivered to its pump, and b) the excess presence of used solution collected off...
Pots water alarm circuit
The flowers in pots require watering, as relying solely on the observation of moist soil surfaces can be unreliable. To address this issue, a flower watering indicator has been developed. This circuit includes a field effect transistor (VT1), a second...
