  • NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term "NodeMCU" by default refers to the firmware rather than the development kits. The firmware uses the Lua scripting language. It is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson, and spiffs.

  • HX711 Load Cell Amplifier Module

    SKU: E-386 75.00 +GST
    HX711 is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32.
  • SIM 900 GSM/GPRS Module

  • Voltage Detection Sensor Module 25V

    SKU: E-381 65.00 +GST

    Inputs

    • GND –  This is where you connect the low side of the voltage you are measuring.   Caution! : This is the same electrical point as your Arduino ground.
    • VCC:  The is where you connect the high side of  the voltage you are measuring

    Outputs

    • S:  This connects to your Arduino analog input.
    • – (or minus):  This connects to your Arduino ground.
    • :  This is not connected.  It does absolutely nothing.

  • MF RC522 is a highly integrated read and write card chip applied to the 13.56MHz contactless communication.It is a low-voltage, low-cost, and small-sized non-contact card chip, a best choice for intelligent instrument and portable handheld devices. The MF RC522 uses advanced modulation and demodulation concept which fully presented in all types of 13.56MHz passive contactless communication methods and protocols. In addition, it supports rapid CRYPTO1 encryption algorithm to verify MIFARE products. MFRC522 also supports MIFARE series of high-speed non-contact communication, with a two-way data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz highly integrated reader card series, MF RC522 is much similar to the existing MF RC500 and MF RC530 when there are also great differences. It communicates with the host machine via the serial manner which needs less wiring. You can choose between SPI, I2C and serial UART mode (similar to RS232), which helps reduce the connection, save PCB board space (smaller size), and reduce cost.
