  • Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, position limit, etc. In principle, any rate meter simply measures the rate at which some event occurs. Usually this is done by counting the events for a given period of time (integration interval) and then simply dividing the number of events by the time to get the rate.
  • This is a 12V 1-Channel Relay interface board which can be controlled directly by a wide range of micro controllers such as Arduino, AVR, PIC, ARM, 8051 and so on. It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc High quality screw terminals (Terminal Block) provided (C, NC , NO) for quick and easy connection LED Status indicators to indicate the relay ON/OFF status.
  • DS1302 Real Time Clock RTC Module

    SKU: E-230 50.00 +GST
    The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM.  It communicates with a microprocessor via a simple serial interface.  The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information.  Only three wires are required to communicate with the clock/RAM: CE, I/O (data line), and SCLK (serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1μW.  The DS1302 has dual power pins, one for primary and another for backup.
    • Input: DC 3V to 40V (input voltage must be higher than the output voltage to 1.5v above can not boost)
    • Output: DC 1.5V to 35V voltage continuously adjustable, high-efficiency maximum output current of 3A.
    • Features: All solid capacitors, the 36u thickening circuit boards, high-Q inductance with output value of high-power LED indicator
    • Dimensions: 45 (L) * 20 (W) * 14 (H) mm (with potentiometer)
  • he 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. Introduced in 1971 by Signetics, the 555 is still in widespread use due to its ease of use, low price, and stability. It is now made by many companies in the original bipolar and also in low-power CMOS types. This module is use as a square-wave signal generator.  It generates square wave signals used for experimental development. It also generates square wave signal driving motor drive.  With adjustable pulses generated for use by the MCU and adjustable pulse control related circuits.
    • Can detect flame or wavelength of light source within 760nm~1100nm.
    • Lighter flame detect distance 80cm.
    • Greater the flame, farther the test distance.
    • Detect angle: 60 degree, very sensitive with flame spectrum.
    • The sensitivity is adjustable.
  • The DS1990A serial number IButton is a rugged data carrier that serves as an electronic registration number for automatic identification. Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return. Every DS1990A is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel iButton package is highly resistant to environmental hazards such as dirt, moisture, and shock. Its compact coin-shaped profile is selfaligning with mating receptacles, allowing the DS1990A to be used easily by human operators.
