Makeblock Sensor "Gas Sensor V1" / Gas for MINT Robot. Me gas sensor contains MQ2 type smoke sensor, which has good repeatability, long-term stability, short response time and durable working performance. It is widely used as a gas leakage monitoring device in family and business, and is suitable for detecting liquefied natural gas (LNG), butane, propane, methane, alcohol, hydrogen, smoke and so on. Its black ID means it has an analog port and must be connected to the port with the black ID on the Makeblock Orion.   technical specifications Operating voltage: 5.0V ± 0.1 V Heating voltage: 5.0V ± 0.1 V Heating resistance: 33Ω ± 5% (at room temperature) ?

Relative humidity: < 95%RH Oxygen concentration: 21% (in standard condition) Module dimensions: 51 x 24 x 18mm(L x W x H) Functional characteristics: The white surface of this module is the reference surface for the contact area of the metal supports Adjustable resistor to set the sensitivity Preheat for a while before use to keep it warm after preheating Blue indicator lights up when a certain amount of combustible gas has accumulated and is detected. Provide output port for digital and analog signal Strong stability and fast detection Support mBlock GUI programming, and applicable for users of all ages Adopt RJ25 jack for easy connection Provide pin type port to support most development boards including Arduino series   Pin definitions: The Me gas sensor connector has three pins, and their functions are as follows:   Connection Connection with RJ25 Since the connector of the Me-Gas sensor has a black ID, you need to connect the connector with the black ID on the Makeblock Orion when you use the RJ25 connector. Using the Makeblock Orion as an example, you can connect ports #6, #7, and #8. Connection with dupont wire If the dupont wire is used to connect the module to the Arduino UNO baseboard, its DO pin should be connected to the digital port   Principle Me Gas Sensor has an adjustable resistor to adjust the sensitivity of the sensor to the smoke. The smoke concentration depends on the distance between the sensor and the smoke source. In the same environment, the closer the distance, the higher the smoke concentration; the farther the distance, the lower the smoke concentration. Therefore, it is necessary to set a voltage value that corresponds to the corresponding smoke concentration threshold.   Detection principle: MQ-2 type smoke sensor uses tin oxide as gas-sensitive semiconductor material, which acts as N-type ionic semiconductor on the surface. When the temperature is in the range of 200~300?, the tin oxide adsorbs the atmospheric oxygen and forms negative oxygen ions, so that the electron density of the semiconductor is decreased and its resistance is increased. When the potential energy barrier at the grain boundary is modulated by the smoke when in contact with smoke, its change causes the conductance to change. From this, one can obtain the information whether the smoke exists or not. The greater the smoke concentration, the greater the conductance and the lower the output resistance. The decrease of the mass resistance of the sensor leads to an increase of the output voltage to ground. By comparing the output voltage and the threshold voltage using the comparator on the module, the concentration of the detected smoke can be determined.

"Makeblock Sensor "3-Axis Accelerometer and Gyro Sensor V1" / Accelerometer & Gyroscope for MINT Robots" The Me 3-axis accelerometer and gyroscope sensor is an ideal module for robot motion and posture detection. It contains a 3-axis accelerometer, a 3-axis angular velocity sensor and a motion processor, and provides an I2C port for communication. It can be used on the self-balancing cart, 4-axis aircraft, robots and mobile devices. It has the advantage of high dynamic range and low power consumption. Its white ID means it is in I2C communication mode and should be connected to the port with white ID on Makeblock Orion.   Functional characteristics Input voltage: 5V DC Signal mode: I²C communication Module size: 51 x 24 x 18 mm (L x W x H)   Pin definitions The port of Me 3-axis accelerometer and gyro sensor has 4 pins, and their functions are as follows:   Connection Connection with Rj25 Since the port of Me 3-axis accelerometer and gyro sensor has white ID, you need to connect the port with white ID to Makeblock Orion when using RJ25 port. Using the Makeblock Orion as an example, you can connect it to ports #3, #4, #6, #7, and #8. Connection with Dupont Wire If the module is connected to the Arduino UNO baseboard using the dupont wire, the SCL and SDA pins should be connected to the I2C port, i.e. port A5 and A4 respectively.   Principle The Me 3-axis accelerometer and gyro sensor integrates a 3-axis accelerometer, a 3-axis angular rate sensor (gyro), and a digital motion processing engine (DMP), and outputs the integrated 9-axis synthetic data as a single data stream to the application client via the I2C port. The 3-axis accelerometer can measure the change in acceleration in the X, Y, and Z axes. By sensing the total inertial force in a certain direction, the accelerometer can measure acceleration and gravity. The 3-axis accelerometer means it can detect the motion or gravity of an object in 3D space. The accelerometer can be used to measure gravity g. When the module is still and completely motionless, the force exerted on it by the Earth's gravity is approximately 1 g. If it is placed vertically, it will detect the force acting on it along the Y axis, about 1 g. If it is set up at a certain angle, it detects that the force of 1 g is distributed along different axes. When it is in motion or vibrating in 3D space, the Me 3-axis accelerometer and gyro sensor will detect the force of more than 1 g in one or more axes as well as acceleration. Velocity and displacement can be determined by integrating the acceleration. When an object rotates around an axis, the angular velocity is generated. The 3-axis angular velocity sensor (gyro) can detect the change in angular velocity in the X, Y, and Z axes. The motion processing engine can output data directly through the I2C port, which reduces the load on the peripheral microprocessor and avoids complicated filtering and data synthesis.
