Schematic Diagram Anti Theft Car wireless alarm
This is an anti-theft alarm with wireless connectivity, referred to as the Anti-Theft Car Wireless Alarm. The FM radio-controlled anti-theft alarm can be utilized with any vehicle that operates on a 6 to 12-volt DC supply system. The mini VHF...
Garage door open indicator
There are battery-powered wireless systems available, but the ones encountered would indicate that the door was open even if it was left ajar for ventilation. A system was desired that would alert when the door was fully raised. Additionally, it...
SENSITIVE RF VOLTMETER
This schematic illustrates a peak-reading diode voltmeter that is powered by two amplification stages. A 100 µF capacitor is utilized to create a substantial time constant, which ensures effective damping of the meter. The restricted differential output voltage, combined with...
field strength meter fsm
A field strength meter circuit is a valuable device for measuring the RF output of any transmitter or for experimenting with different antennas connected to the transmitter. The operation of the field strength meter (FSM) is straightforward; it converts RF...
Carport wireless alarm circuit a
The alarm circuit is composed of two main components: the transmitter and the receiver. The transmitter circuit, as illustrated in Figure A, features a smoke break reed switch labeled GT. When a magnet approaches the GT, the internal contacts open....
DF data transmission module and the super-regenerative receiver module
The DF data transmission module operates at a frequency of 315 MHz and utilizes a surface acoustic wave (SAW) resonator for frequency stabilization, ensuring high frequency stability. The frequency drift remains minimal, at only 3 x 10^-6, across a temperature...
2 Channels RF remote control
Remote controls are often needed to manage various electric devices. There are several types of remote controls available, including infrared, RF (Radio Frequency), and SMS. Basic short-range remote controls primarily utilize infrared and RF technology. A limitation of infrared is...
RF Field Strength meter
As I used this probe last night to determine if a 384 MHz oscillator was really working or not, I remembered an email I received a while ago, asking how to make a field strength indicator without the microcontroller. Thus...
door opener science project
This button, with some modifications, allows the opening of an office door using Nexus One, iPhone, or SMS. Positioned near the reception desk, this button activates an electronic latch on the front door. Upon removing the assembly from the wall,...
