Use method: Product feature HC-SR04 ultrasonic module can offer non-contact distance sensing function. The range of which is 2cm—400cm. and the range accuracy is up to 2mm; the module includes ultrasonic transmitter, receiver and control circuit. The basic operation principle is below: use IO port TRIG to trigger ranging. It needs 10 us high level signal at least• Module can send 8 pro 40 kz square wave automatically. And will test if there is any signal returned. If there is signal returned. Output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic. Testing distance =duration of high level*sound velocity(340m/s) 2. Physical map Refer to the wiring diagram below. VCC supply 5V. And GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output. Picture 1: Physical map• electric parameter Electric parameter HC-SR04 ultrasonic module Operating voltage DC 5V Operating current 15 mA Operating frequency 40 Hz Utmost range 4 m Nearest range 2cm Measure angel 15 ° Input trigger signal 10uS TTL pluse Output echo signal Output TTL level signal.

1pc HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module SKU: A876 Description Electrical parameters: Product Type: HC-SR501 Body ... moreSensor Module Operating voltage range: DC 4.5-20V Quiescent Current: Level output: High 3.3 V/Low 0V Trigger: L can not be repeated trigger/H can be repeated trigger(Default repeated trigger) Delay time: 5-200S(adjustable) the range is(0.xx second to tens of second) Block time: 2.5S(default)Can be made a range(0.xx to tens of seconds Board Dimensions: 32mm*24mm Angle Sensor: Operation Temp: 15-+70 degrees Lens size sensor: Diameter:23mm(Default) Features: 1. The automatic sensor: to enter the sensor output range is high, people leave the sensor range of the automatic delay off high. Output low. 2.The photosensitive control(optional, factory is not set) may set the photosensitive control during the day or light intensity without induction. 3. The temperature compensation(optional, factory is not set) In the summer when the ambient temperature rises to 30 ~ 32 ℃. Slightly shorter detection range, temperature compensation can be used as a performance compensation. 4. Two trigger mode: can be selected by jumpers) a. Can not repeat the trigger: the sensor output high, the delay time is over, the output will automatically become low from high; b. Repeatable trigger: the sensor output high after the delay period, if the human body in its sensing range activities, its output will remain high until after the delay will be left high to low(sensor module review Measured activities of each body will be automatically extended after a delay time, and the final event of the delay time Starting point of time) 5. With induction blocking time(the default setting: 2.5S block time) sensor module, after each sensor output(high change Into a low level) you can set up a blockade followed by time period, in this time period the sensor does not accept any sensor signal. This feature can have a"sensor output time" and"blocking time" the interval between the work produce

Photodiode module is most sensitive to the ambient light. Generally used to detect the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the difference between the two is that photodiode module directional, can sense the fixed the direction of the light source. 2. Module in the light conditions or the light intensity of less than a set threshold. DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low; 3. The small board digital output D0 can be connected directly with the microcontroller microcontroller to detect high and low to detect environmental light intensity change; 4.
