Hello,
I try to connect si1145 module from adafruit to Arduino MKR 1310 to access the data. But I find that it cannot output stable as shown in the picture. This is a very simple test and this si1145 module can work with Arduino Nano without any problem.
The code I use is this:
#include <Wire.h>
#include "Adafruit_SI1145.h"
Adafruit_SI1145 uv = Adafruit_SI1145();
void setup() {
Serial.begin(9600);
while(!Serial);
Serial.println("Adafruit SI1145 test");
if (! uv.begin()) {
Serial.println("Didn't find Si1145");
while (1);
}
Serial.println("OK!");
}
void loop() {
Serial.println("===================");
Serial.print("Vis: "); Serial.println(uv.readVisible());
Serial.print("IR: "); Serial.println(uv.readIR());
// Uncomment if you have an IR LED attached to LED pin!
//Serial.print("Prox: "); Serial.println(uv.readProx());
float UVindex = uv.readUV();
// the index is multiplied by 100 so to get the
// integer index, divide by 100!
UVindex /= 100.0;
Serial.print("UV: "); Serial.println(UVindex);
delay(1000);
}
