Any question please contact via contact@bsfrance.fr
What you need:
1PCS Arduino UNO
1PCS USB Cable
1PCS AS3935 Light Sensor
6P Female to Male Dupont Cable
Connection:
AS3935 Arduino UNO
VCC 5V
GND GND
SCL A5
SDA A4
IRQ D5
First you need use IIC.ino to find the IIC address of the AS3935 sensor
Then you need change IIC address in the AE_AS3935DEMO-.ino, upload the code and open the serial monitor, please choose 9600 baud.
In my case, I changed the Line 11 and Line 66 to 0x03
11 #define AS3935_ADRS 0x03 66 Wire.write(0x03);
Below is the result

Recently, one customer complained:
I bought a U-blox 7 from you and I’m giving it some tests right now and I’m not getting correct readings from it. I’m an application developer and I had to add a compensation element to both latitude and longitude in order to get “correct” readings from it.
GPS data to google data need conversion
Here is the link about how to do it https://drive.google.com/open?id=1MwNTrqJtst3Dpl9qH8Mt3UJhs87ODdf9
1 . Connect the board like this, one micro usb cable to computer, power the SIM7100A board ( pins is supply and GND, you can use DC Power supply to power the board . Power supply voltage:5V-18V, current about 1.0A, you can adjust the current until the PWR LED turn on
2 . Download document link

User name and password is diymall
3 . Press the switch until the 2 LEDs turn on (PWR and STA)
4 . Open device manager, then you will see
5 . Right click to install the driver, you need install the driver manually, find the driver file and install it for about 5 times ( you need choose the right system file)
6 . Then the computer will inform you to install the driver, just click and install the driver . After installing, please find the COM port in the device manager
7 . Open SIMCom Wireless Kit software, choose the Simtech Hs-USB AT Port 9001 (here is COM23), click open port, you can input AT commands in the e.g blank place, like AT, ATI

Servo control generally requires a base pulse about 20MS，if the degree is not 180 degree, you need adjust the base pulse in the Arduino code
0.5ms—0 degree
1.0ms—45 degree
1.5ms-—90 degree
2.0ms — 135 degree
2.5ms— 180 degree
Below is Arduino code:
#include <Servo.h>
Servo servo1;
void setup()
{
servo1.attach(3);
servo1.writeMicroseconds(2500); // = -90°
delay(500);
servo1.writeMicroseconds(500); // = 0°
delay(500);
servo1.writeMicroseconds(1500); // = 90°
delay(500);
servo1.writeMicroseconds(2500); // = -90°
delay(500);
servo1.writeMicroseconds(500); // = 0°
delay(500);
servo1.writeMicroseconds(1500); // = 90°
delay(500);
}
void loop() {}
