Product description
Noise sensor
use a microphone with an amplifier to detect the sound level of the environment. It will capture the
original sound wave, enlarge it, and reproduce it in voltage form. When using the sensor to calculate thesound level, use the amplitude to decide the result.
Specifications:
Supply voltage: 3.3V – 5V
Interface: Analog
Output Range: 0~3.5V
The Distance sensor
using two ultrasonic sensors to detect the distance between current position and object. In most
situation, the availability of ultrasonic allow it provided quick and accurate result.
Specifications:
Supply voltage: 5V
Working Frequency: 40kHz
Range: 3cm to 4m
MeasuringAngle:
The Light sensor
use one photoresistor to detect the luminance of environment. The darker of the environment, the lowervoltage will be provided.The Light sensor also call as Light Dependent Resistor(LDR), the physical
property will change under different light source as the name implied. Depend on the model of differentLDR, the resistance value and curves have difference, but all follow the principle: When the Illumination
is increase, the resistance of the resistor will reduce. When the Illumination is decrease, the resistance ofresistor will increase.
Specification:
Supply Voltage: 3.3V to 5V
Interface: Analog Output Voltage
Range: 1%~90% of supply
Voltage Reading in the PXT(with Mirco:bit): 1~100(0.04V~3.3V)
The Temperature and Humidity Sensor (DHT11)
contain two major components to detect humidity and temperature respectively. The first component is using the Conductivity to measure the environment humidity. When humidity is changing, the polymer
between two electrodes will change the conductivity, causing the resistance between electrodes drop
or rise. The chip on DHT11 will use it to determine correct humidity. For the second component on DHT11it is a Negative Temperature Coefficient(NTC) thermistor, when the temperature is rising, the resistance will decrease as follow. The chip will use that to determine the environment temperature.
Specifications:
Supply Voltage: 3.3V to 5V
Range of Temperature reading: 0-50°C with +- 2°C accuracy
Range of Humidity reading: 20%~80% with +- 5% accuracy
The Motion Sensor
use a pyroelectric infrared sensor to detect any moving object at front.When the infrared signal have
rapid change, the sensor will return high to user, otherwise, return low.
The pyroelectric infrared sensor will keeping record the infrared signal inside target area. Human will
emit the infrared light cause by the body temperature, when they pass thought the detection area, the
signal received by sensor will have fluctuation which can determine the movement of object. Generally,
the maximum range of the detection is 5 to 12 meters , create a spherical sector with 65 degree from
normal line.
Specification:
Supply Voltage: 3.3V
Interface: Analog
Operation Temperature: -20 ~ 85°C
Angle of detection:
Raindrop sensor
use the Conductivity to determine the rain drops is on the board or not, when there are no liquid on the board, the reading will be very small (0 if no liquid), however even one drop of rain, can increase the
conductivity very much and make the reading to extremely high (100).
The RainDrop Sensor use the conductivity between the two electrodes to determine the change of the water drop on the plane. When there is no water drop on the plane, the material between the two
electrodes is air, result in very low conductivity. However, when the water drop is on the plane, the
conductivity between the electrodes will become very high since water is a good conductor.
Specification:
Supply Voltage: 5V
Interface: Analog
Range: 0(Dry surface) ~ 100(WaterDrop on surface)
