  • HC-06 RF Wireless Bluetooth Transceiver Slave Module RS232 / TTL to UART converter and adapter. This module is an Upgrade from the older HC-05 and has better stable Firmware. Features: Bluetooth Serial Transceiver Module with backboard. This module includes key interface and state interface compared with Smart Bluetooth Module Baseboard. The Bluetooth Module Baseboard can be compatible with slave mode. Works for Bluetooth TTL transceiver module which allows your target device to both senders receive the TTL data. The key interface on the baseboard is the master mode button and can be controlled by high level from external MCU, and then this module will search again automatically. Built in antenna Bluetooth version: V2.0 EDR
  • This module integrates DHT11 sensor and other required components on a small PCB. The DHT11 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component and a high-performance 8-bit micro controller inside, and provides calibrated digital signal output. It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology.
  • TCS3200 TCS230 Color Sensor Module

    SKU: E-39 750.00 +GST
    The TCS230 programmable color light-to-frequency converter combines configurable silicon photodiodes and a current-to-frequency converter on single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The full-scale output frequency can be scaled by one of three preset values via two control input pins. Digital inputs and digital output allow direct interface to a microcontroller or other logic circuitry. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.
  • L293D Motor Driver Board

    SKU: E-40 120.00 +GST
    L293D Motor Driver Board E-40 L293D Motor Driver shield Input Voltage Range: 4.5 To 24VDC Output current Per Channel: 600mA Peak Output current: 1.2A
  • DTMF Module

    SKU: B-33 130.00 +GST
    DTMF Refers to Dual Tone Multi-Frequency Signaling. This DTMF is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center.
  • This module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.
  • 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.
  • This is a 4 channel relay module. It can be used to control the lighting, electrical and other equipment. The modular design makes it easy to expand with the Arduino board or other MCU board PIC, ARM and MSP430. The Relay output state by a light-emitting diode.
  • The 8 channel 12V relay module provides 8 optically isolated inputs that accept a wide range of voltage. This is a great way to switch on or off AC or DC loads using your Arduino. The relays are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals. This, along with the optical isolation, provides a total galvanic isolation between the input and output. The two grounds could be joined together if desired with the included jumper. The relay coils run on 12VDC, and the module has screw-terminal blocks for sturdy and reusable attachments for the external load. The signal and power inputs run through the male single-row header.
  • FLEX SENSORS 2.2 “

    SKU: E-50 275.00 +GST
    A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly. Check datasheet for full specifications.
  • FLEX SENSORS 4.5 “

    SKU: E-51 700.00 +GST
    A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly. Check datasheet for full specifications.
  • The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane ,alcohol, hydrogen and smoke.
  • This module is made using Alcohol Gas Sensor MQ3. It is a low cost semiconductor sensor which can detect the presence of alcohol gases at concentrations from 0.05 mg/L to 10 mg/L. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of alcohol gases increases. It has high sensitivity to alcohol and has a good resistance to disturbances due to smoke, vapor and gasoline. This module provides both digital and analog outputs. MQ3 alcohol sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc.
