This item is a 5V 4 Channel Relay board, Can be able to control various appliances, and the other equipments with large current. It can be controlled directly by Microcontroller Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic.
The company produces relay module can be connected to 240V AC or 28V DC power into a variety of other electrical parts. The relay can be used in anti-theft alarm, toys, etc. Relay is an electrically controlled device. It has a control system (also known as the input circuit) and the control system (Also known as the output circuit).
Commonly used in automation control circuit, it is actually a small Current to control a large current operation "automatic switch." Therefore, the circuit automatically adjusts the play, safety protection, transfer Conversion circuit and so on. Particularly suitable for single-chip control strong electric devices. In the control and use is also very convenient, just give input corresponding output relay different levels, you can Achieved by controlling the relay control purposes other devices, in addition, in the multi-channel relay PCB layout on the use of two lines Layout, user-lead connections. While in the circuit of a DC diode added greatly improved relay
Module to engage current ability to prevent the transistor being burned. In addition, we added a relay this power indicator Lights (except relay all the way), the indicator is red. In brightest relay also adds a status indicator.
Reed module and the interface comes with digital 13 LED build a simple circuit to produce a Reed warning lamp 13 comes with digital interfaces of the LED, the Reed sensor access number 3 interface, when Reed sensors Sensed a key signal (magnetic field change near the module), LED lights, otherwise off.
Linear Hall magnetic module and a digital interface, built-in 13 LED build a simple circuit to produce a magnetic field warning lamp 13 comes with digital interfaces of the LED, the linear Hall sensor magnetometer access number 3 interface, when linear Hall magnetometer Sensor senses a key signal, LED lights, otherwise off.
The KY-003 is a magnetic switch. If no magnetic field is present, the signal line of the sensor is HIGH (3.5 V). If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time the LED on the sensor lights up. The polarity of the magnetic field is of influence to the switching action. The front side of the sensor needs the opposite polarity as the back of the sensor to switch on.
In the example program the led on the Arduino (pin 13) will be turned on when a magnetic field is present.
KY-035 is an analog magnetic field sensor module. The strength of the field is given by an analog voltage at the signal pin of the module KY-035. The sensor is connected to gnd and 5V of the Arduino board. The output voltage is measured by analog pin A5 on the Arduino board.
The example program measures the output voltage of the sensor en presents the measured value in the serial monitor of the Arduino.
The led on the board flashes in a speed depending on the strength of the magnetic field. With a small magnet this can be demonstrated.
his ALSRobotBase Ceramic Piezo Vibration Piece Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vibration.
When the piezoelectric ceramic shocking will generate an electrical signal, Arduino Controller analog port can be perceived slight vibration signals, Also can be realized with vibration interactions related works, such as electronic drums.
