Electric Socket Wall AC Power Outlet Voltage Detector Sensor Tester Pen 90-1000V
The next generation AC non-contact voltage testers are easy to use ? just touch the tip to a terminal strip, outlet, or supply cord. When the tip glows red and the unit beeps, you know there is voltage present. Electricians, maintenance, service, safety personnel, and homeowners can quickly test for energized circuits in the workplace or at home.
Frequency Range: 50 to 500 Hz
Test Voltage Range: 90-1000V AC
Safety Rating : CAT II 1000v
Powered By: 2 x AAA Batteries (Not included)
A perfect tool kit for home and electric industry uses
Ideal design for testing power cables, circuit breakers, wall sockets, junction boxes, fuses, etc
Just press the button, white LED light can be always on when there is absence of voltage
"Beep" sound and red flashing LED would indicate the presence of voltage
Totally insulated, no exposed metal or conductive parts
Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes (including dual diode), thyristors, transistors, resistors and capacitors and other components,
Automatic test out the pin element and displayed on the LCD
Can be detected to determine the transistor emitter forward bias voltage of the transistor, MOSFET protection diode and the amplification factor of the base
Measure the gate threshold voltage and gate capacitance of the MOSFET
LCD display uses LCD 1 2864
High test speed, valid component test: 2 seconds (except in the larger capacitor of large capacitance measurement also takes a long time, the measured time of one minute is normal)
6. Data upload real time,the max of depth of collection is 10T,far from practical need.
A total of eight digital channels, =voltage range is 0V ~ 5.5V, the voltage threshold is considered to be low below 1.5V, 1.5V above is considered high.
Package includes the main device, 10pins of dupont cable and one USB cable.
See basic how it works and how to use the introduction video below.
Samples : How much samples to collect, Mhz: frequency of sampling, so 50M * 1Mhz will be 50 total sampling time.
This one is a starter version, different to Saleae16, which has 100Mhz, 16-channel version
The company produces PS2 game joystick axis sensor module consists of using original quality metal PS2 joystick potentiometer system For the (X, Y) a 2-axis analog output and for (Z) 1 digital output channel button.
This device uses your body as part of the circuit. When you touch the sensor pad, the capacitance of the circuit is changed and is detected. That detected change in capacitance results in the output changing states.
When I first got this, I expected a glitchy device, that while functional, would occasionally have unpredictable output results.
I may have been wrong. After playing for a few hours, I can’t seem to get it to do anything other than what I expected it to do. If you’re looking for robust user input, this might do the trick.

What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one's own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.
Electronic brick of button switch is finger-sized, which can be connected to I/O port of main board or externally disconnected to check the switch state so as to control ON/OFF of LED lamp.
Features:
1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock
3. Hardware with debouncing function for more stable output
By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which Species rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0.
How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. These pulses are used to control Angular displacement. In Eltra angular displacement encoder conversion using a photoelectric scanning principle. Reading system of alternating light transmitting window and the window is not Consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving
On the surface. Receiver is covered with a diffraction grating, which has the same code disk window width. The receiver's job is to feel the rotation of the disc Resulting changes, and change the light into corresponding electrical changes. Then the low-level signals up to a higher level, and generates no interference Square pulse, which must be processed by electronic circuits. Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms Different by 180 ° compared to the signal in order to improve the quality and stability of the output signal. Reading is then the difference between the two signals formed on the basis, Thus eliminating the interference.
