    Raindrops Sensor Module MH-RD

    NPR 350.00

    The rain sensor module is an easy tool for rain detection. It can be used as a
    switch when raindrop falls through the raining board and also for measuring rainfall
    intensity. The module features, a rain board and the control board that is separate for
    more convenience, power indicator LED and an adjustable sensitivity though a
    potentiometer. The analog output is used in detection of drops in the amount of rainfall.
    Connected to 5V power supply, the LED will turn on when induction board has no rain
    drop, and DO output is high. When dropping a little amount water, DO output is low, the
    switch indicator will turn on. Brush off the water droplets, and when restored to the initial
    state, outputs high level.

    Sim 800A with Antenna

    NPR 3,000.00

    The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a complete Quad-band GSM/GPRS solution in an LGA(Land grid array) type which can be embedded in the customer applications. SIM800A support Quad-band 850/900/1800/1900 MHz, it can transmit Voice, SMS and data information with low power consumption.

    With a tiny size, it can fit into slim and compact demands of custom design. Featuring and Embedded AT, it allows total cost savings and fast time-to-market for customer applications.

    The SIM800A modem has a SIM800A GSM chip and RS232 interface while enables easy connection with the computer or laptop using the USB to the Serial connector or to the micro-controller using the RS232 to TTL converter. Once you connect the SIM800A modem using the USB to RS232 connector, you need to find the correct COM port from the Device Manager of the USB to Serial Adapter.

    Then you can open Putty or any other terminal software and open a connection to that COM port at 9600 baud rate, which is the default baud rate of this modem. Once a serial connection is open through the computer or your micro-controller you can start sending the AT commands. When you send AT commands for example “AT\r” you should receive back a reply from the SIM800A modem saying “OK” or other response depending on the command sent.

    Solenoid Valve (0.5″ 12V)

    NPR 1,350.00

    A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
