3) IoT Internet Control Toy
4) Unmanned security
5) Pet helper



1) GT-IoT900 is the training System that can learn about IoT, IoT design principle, and learn about how to
implement IoT Application.
2) transfer the collected & gathered date from farm, factory / school / office / building, houses & apartment to
smartphone in real-time.
3) provides a fun and easy developing environment in which to make your ideas in a reality.
4) Each application examples are consisted of Gateway (Raspberry Pi) S/W, Sensor S/W, Actuator S/W,
Smartphone Application S/W.
5) Gateway works with variety of sensors (temperature, humidity, light intensity, movement, sound, flame,
smoke, gas, soil Temperature / Humidity, cameras, etc.)
And it controls the various actuators (Relay, LED, Buzzer, Sound, flashing lights, Piezo Siren, Pump, Motor, etc.)
6) Through a smartphone app, you can implement a variety of scenarios in response to the video and sensor data.
7) GT-IoT900 offers Firmware, Web program, smart phone (for Android) software examples necessary to various
application design / practice.

  • (5) 8 kinds of sensor module - inter-working with Raspberry Standard GPIO Headers(40pin)
  • Gas sensor by the mounted heater & sensor, can detect ammonia, contaminated gas.
    Motion setection sensor IR coming from the human or animal body has a wavelength of about 10㎛.
    Respond when detect the wavelength.
    Temperature / Humidity Sensor Combined one for Temperature sensor & Humidity sensor.
    Proximity Sensors May be measured about 10 ~ 80cm away, the output voltage changes
    according to the distance to the sensor module
    Ultrasonic Sensors The ultrasonic sensor emits a short sound through high-frequency pulses at regular
    intervals. These are spread in the air through the speed of sound and sensing the
    reflected echo signal that is made by colliding with an object.
    Acoustic sensors
    by detecting the ambient sound, emit it to analog signal or digital signal.
    Flame Sensor detect flame wavelength (frequency, 760nm~1100nm) at a distance of about 1m around.
    Light sensor Detect by converting light itself or information of light into electric signals.
