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 produced can be applied to detect the interval Products; also inhibit this function during load  
switching for a variety of interference. (This time can be set at zero seconds - Tens of seconds). 
6, the working voltage range: the default voltage DC4.5V-20V. 
7, micro-power consumption: static current "50 microamps, especially for battery-powered automatic control products.

0-3 times a minute in standby mode. 
2. Should avoid direct lighting such as interference sources close the surface of the lens module so as to avoid the  
introduction of interference signal generator malfunction; use of the environment to avoid the flow of the wind, the  
wind sensor will also cause interference. 
3. Sensor module using a dual probe, the probe\'s window is rectangular, dual (A per B million) in the direction of  
the ends of long, when the body passed from left to right or right to left when the reach the dual IR time, distance  
difference, the greater the difference, more sensitive sensors, when the body from the front to the probe or from top  
to bottom or from bottom to top direction passing, dual IR not detected changes in the distance, no difference value,  
the sensor insensitive or does not work; so the sensors should be installed dual direction of the probe with human  
activities as much as possible parallel to the direction of maximum to ensure that the body has been passed by the  
dual sensor probe. To increase the sensing range of angles, the module using a circular lens, the probe also makes sense  
on all four sides, but still higher than the upper and lower left and right direction of sensing range, sensitivity and  
strong, still as far as possible by the above installation requirements.VCC, trig (control side), echo (receiving end), GND

Things history of this concept has been five or six years, but has never really into life! The reason is as follows: Things have to be regarded networking things, but to get networked household appliances, before costly price overshadowed main circuit board! Therefore lingering large area applications. But only a matter of time! We waited for 3-5 years, various radio manufacturers, network equipment design giants have all eyes on this market, as we all know: If the price down, the demand is huge, the initial conservative estimate of global demand at 1.5 billion stars of the annual demand. So TI's CC series Qualcomm QCA400X series MTK's MT76XX series and East China Normal University and Taiwan have several research and development capabilities, have started in April 2014, are small quantities to test the water! And at the beginning of June 2014 to July have to market prices from over 50 over 40 over 30 over 20 dollars, this is just the price strategy between suppliers, but their marketing strategies must comply with market rules and people's spending power, in order to get large quantities of promotion, WIFI chip prices must be the product of the proportion of things in the whole BOM costs must be lower than 30% in order to get a large area, but before June 2014 a, WIFI cost module in the customer material costs accounted for almost 60% of the cost! Clearly this is unreasonable, and hindered the pace of development of this industry.
 
According to market rules: analysis of the current market can have several competitive WIFI chip manufacturers, although each one has launched its own WIFI chip, and input costs millions of tens of millions. But the real survive, and only one or two. Because their production process, and design, as well as application experience, and price positioning of customers. And China's market, can truly unified market presumably only one! Is simply cruel reality. Things in the upcoming initial flourish, can choose a truly competitive chips. That is for the future development of crucial! We do not want the wrong team. . .
 
In the absence of more cattle X chip out now is the most cattle X.
 
After the recent trends in the situation more than a month, almost shocking, because the whole market is that several have made tremendous feeling!
 
Let us appreciate: no final finisher, simply because most cattle X, it has not yet appeared. . . . Everything is just the beginning! !
 
But things really make the entire industry toward the climax is: the emergence of Shanghai Yue Xin Technology ESP8266 chip. They incredible
 
Hardware and software update rate, and very shocking price advantage to market quickly! So that the entire industry is not a trace of preparedness.
 
Yue Xin advantages:
 
A very professional, Espressif is Shanghai Yue Xin, only WIFI. Several other competitors do more pan.
 
2 staffing more powerful, 30-40 WIFI chip engineers only for this service! None can do it?
 
High professional quality three officers, who CEO for the United States Chief Technology Officer, a well-known listed companies, there are several men Dr. returnees.
 
4 More to the point: a pragmatic! Office area, although not super big, but all are professionals, there is no redundancy in the department, really appreciate it, do not speak face-saving projects, working sense, this is a lot of companies can not do.
 
5 ground gas, Xin Yue contacted each employee, are very enthusiastic and gas. They can efficiently happy to help you solve technical issues and business problems you encounter. In contrast, several other companies: their superior technical personnel operational staff, dragon head, not the tail, are more difficult to want to learn, to reflect on.
 
Very honored that we smooth the fastest chip batch applications, and consignment. We are confident: we launched ESP8266 Series modules are available in the market the most cost-competitive products.
 
We hope that several Espressif the ESP8266 module, allowing your products with a strong competitive advantage. And consignment chip!
 
The industry's smallest, industrial grade stability! The most cost-effective.

(1) Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
 
(2)Under no-load conditions, adjust the"Voltage potentiometer"so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
 
(3)Adjust the right button so that Digital meter shows the value of output current;Wire shorted output terminal, then adjust the"current potentiometer"so that the output current reaches a predetermined Charging current value.
 
(4)Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fullycharged)
 
(5)connected to the battery charge.
 
(1,2,3,4 steps as: Output is unloaded, do not connect the battery)
 
3.Use as a LED constant current driver module
 
Usage:
 
(1)Adjust the"voltage potentiometer"so that the output voltage reaches the value you want.
 
(2)Adjust the right button so that Digital meter shows the value of output current;Wire shorted output terminal, then adjust the"current potentiometer"so that the output current reaches a predetermined LED operating current.
 
(3)Connect LED, work.
 
(1,2 steps as: Output is unloaded, do not connect LED)
 
 
Voltmeter and ammeter calibration method:
 
Module with manual calibration function can correct display precision voltage and current, if you think the current voltage and current accuracy to meet the requirements, do not perform the following operations.
 
(1) Output voltage calibration steps
 
Step 1, adjust the right button so that"OUT"LED lighted, Digital meter shows the value of output voltage; Press the right button for more than 2 seconds, release, Digital meter and"OUT"LED flashes in synchronization so that you enter the output voltage calibration mode.
 
Step 2, press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.
 
Step 3, press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.
 
(2) Input voltage calibration steps
 
Step 1, adjust the right button so that"IN"LED lighted, Digital meter shows the value of input voltage; press the right button for more than 2 seconds, release, Digital meter and"IN"LED flashes in synchronization so that you enter the input voltage calibration mode.
