Introduction Photoresistor in our daily lives but also be able to see, is mainly used in smart switch, giving our students Live brings some convenience, but, in our daily electronic design will also be used. Then in order to make better use,We have the appropriate module, easy to use, and efficient. 2. overview Photoresistors are semiconductor photosensitive devices, in addition to having high sensitivity,fast response, consistent with the spectral characteristics and value of good features, but at a high temperature, and humidity in harsh environments, but also to maintain a high degree of stability and reliability, wide pan used cameras, solar garden lights, lawn, detectors, clock, music, cups, gift boxes, mini-Night light, light voice switches, lights automatically switch toys and a variety of light control,light control lighting, lamps and other light automatic opening OFF control field 3. main parameters and characteristics 1>. according to the spectral characteristics of the photoresistor has three photoresistor: Ultraviolet photosensitive resistance, infrared light-sensitive resistors,Visible photosensitive resistance; 2>. the main parameters are as follows: A>. dark current, dark resistance: photosensitive resistance at a certain applied voltage, when the light is not irradiated when the flowing Current is called dark current. Applied voltage and dark current ratio as the dark resistance; B>. Sensitivity: Sensitivity is irradiated by light sensitive resistor, the resistance value (dark resistance) when irradiated with light Resistance value (light resistance) the relative change in values. C>. volt-ampere characteristic curve.Voltage characteristic curves are used to describe the resistance of the applied voltage and the photosensitive photocurrent relationship,On the photosensitive devices, the light current with applied voltage increases. D>. temperature coefficient. Photoelectric effect photoresistor affected by temperature, at a low temperature portion photoresistor photoelectric Sensitive high sensitivity at high temperatures is low. E>. rated power. Photosensitive resistor rated power is allowed for certain lines in the power consumed when the temperature rise High, its power consumption is reduced. DS18B20 Temperature Measurement Sensor Module: Board DS18B20 chip left 3P hole seat easily accessible DS18B20 chip. Pin chip has all the leads, built-in pull-up resistor. Onboard power indicator. Board size: 21 (mm) x10 (mm) Sound Sensor: Size:32mm (L)*17mm(W)*15mm(H) Main chip:LM393, Electret condenser microphone Working voltage:DC 4-6V Features 1>. Signal output indication 2>. Single channel signal output 3>. The output effective signal is low level 4>. When there is sound,outputs low level and the signal light 5>. Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control,sound detect 6>. Circuit board output switch quantity 7>. Reference routines, circuit diagram and detailed specification will be provided after perchase. Flame Sensor Module: Signal output indication Sigle-way signal output Output effective signal is low level Used to detect the heat source within the range from 760nm-1100nm Detect angle can be 60° Circuit board outputs switch quantity.(can connect MCU directly) Rotary Encoder Module: By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. These pulses are used to control angular displacement. In Eltra angular displacement encoder conversion using a photoelectric scanning principle. Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surface. Receiver is covered with a diffraction grating, which has the same code disk window width. The receiver's job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changes. Then the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuits. Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180°compared to the signal in order to improve the quality and stability of the output signal. Reading is then the difference between the two signals formed on the basis,thus eliminating the interference. Soil Humidity Sensor: Supply voltage: 3.3V or 5V Operating current: less than 20mA Output voltage :0-2.3 V [2.3V is completely immersed in water] voltage, 5V power supply, humidity, the greater the output voltage increases.
