Infrared Remote Control for Operates on 115 Volts AC

This circuit will allow you to turn on any piece of equipment that operates on 115 volts ac. The receiver circuit is based on the Radio Shack infrared receiver module (MOD), part number 276-137. It is also available from some of the other sources listed on my Links page. The MOD accepts a 40khz IR signal that is modulated at 4 khz.

Circuit Diagram

When a signal is received the MOD will go low. The sensitivity of the MOD is set by different values for R1 and C1. The values for R1 may need to be as high as 10,000 ohms and for C1 40uf. This will prevent the unit from turning on under normal lighting conditions. You will need to experiment with the values that work best for you. The output of the 4013 chip a flip flop toggles on and off with the reception of a IR pulse. The output of the 4013 turns on the MOC optical coupler which in turn switches on the triac and supplies power to the AC load.

SMS Remote controller circuit

SMS Remote controller is a device used to control a device remotely using SMS through GSM mobile phones. Process control equipment with a series of AVR ATTiny To SMS Remote Controller can be used to control life and death of these equipment will provide information on the status of replies to our phone in return successful command execution.

Equipment can be controlled by a series of AVR ATTiny To SMS Remote Controller include lights, water pumps, garage doors, gates and much more. AVR series ATTiny To SMS Remote controller uses the module-47 Sony ericson GM as recipient and sender of the SMS module. Then to the SMS data processor on a series of AVR ATTiny To SMS Remote controller is using AVR microcontroller ATTiny 2313.

AVR circuit this part ATTiny To SMS Remote Controller

AVR series ATTiny To SMS Remote controller uses the AVR attiny2313 with 4MHz clock frequency, GSM Module GM trnceiver 47 Sony ericson, SIM Card, 4 relays and an IC regulator. ATTiny AVR microcontroller 2313 can work well on the voltage 2.7 VDC - 5.5 VDC for working with the frequency at 10MHz bahwah.

The set of AVR ATTiny In SMS Remote Controller To make use of this power supply from the batteries 3.3 VDC. Connection using a SIM Card SIM Card Holder which is connected to the module GM-47, AVR series ATTiny To SMS Remote Controller works with communication between AVR ATTiny and GM-47 module at 9600bps. In a series of AVR ATTiny To SMS Remote controller is equipped with LED D6 as an indicator of the data interconnect GM-47 module with cellular operators where this LED will light continuously when not apat network and will be lit by flashes when a signal from the operator.

IR Remote Control Tester Circuit Diagram

Here’s a simple, low cost, and easy to construct infrared remote control tester. The tester is built around an easily available infrared receiver module (TSOP 1238).

Circuit Diagram:

Schematic diagram of IR remote control tester IR Remote Control Tester Circuit Diagram

Normally, data output pin 3 of the IR receiver module is at a high level (5 volts)and as such driver transistor T1 is in cut-off state. Whenever the IR receiver module receives a valid (modulated) infrared signal, its data output pin goes low in synchronism with the received infrared bursts. As a result, transistor T1 conducts during negative pulse period and the.LED blinks to indicate reception of signals from the remote such as TV remote control. A miniature active buzzer is connected at the collector of transistor T1 for audio indication.

Proposed enclosure with front-panel

The 5V DC for energizing the circuit is directly derived from the 230V AC mains supply. Unlike the conventional resistive voltage divider, a capacitive potential divider is used here, which does not radiate any heat and makes the tester quite compact. Another advantage of this tester is no false triggering due to the ambient light or electronic ballast-operated tubelights. A suggested enclosure for the circuit is shown in Fig. 2.

Remote Control Receiver

Hello! in this post I will show a remote control receiver, I tested this circuit with an approximate distance of 4 meters and it worked perfectly, the spread of this circuit is that it can be triggered by remote control of multiple devices, I tested with two remote controls one tV receiver and a satellite dish, every time you press a key on the remote, the LED will light up and trigger the relay, the relay output you can connect any device you want to control the 1N4148 diode D4 is also You can add more channels to the circuit, just by connecting the reset of the integrated circuit in 4017 and adding another exit other relés.Assim each pulse sent to the receiver, trigger a relay!

The relay coil has voltage according to the circuit power!

See the figure below:

The receiver used is three terminals, commonly used in television sets!
