BH1750 Lightmeter for Home Weather Station

Another sensor to add to the collection for my Home Weather Station project. I’m adding a Lux level sensor so that I can record the Lux levels thorughout the day. Not sure what for yet, perhaps for some automated sensors, or just to add to it. The more sensors the merrier I say. The better the readings and the more data you can log

What code am I using?

This is the code I’m using on my ESP8266 mini. I’m switching because my Arduino Nano doesn’t have built in WiFi and this device is more powerful and supports Arduino

 

#include <BH1750.h>

#include <Wire.h>

BH1750 lightMeter;

void setup() {

  Serial.begin(115200);

  // Initialize the I2C bus (BH1750 library doesn’t do this automatically)

  Wire.begin();

  // On esp8266 you can select SCL and SDA pins using Wire.begin(D4, D3);

  // For Wemos / Lolin D1 Mini Pro and the Ambient Light shield use

  // Wire.begin(D2, D1);

  lightMeter.begin();

  Serial.println(F(“BH1750 Test begin”));

}

void loop() {

  float lux = lightMeter.readLightLevel();

  Serial.print(“Light: “);

  Serial.print(lux);

  Serial.println(” lx”);

  delay(500);

}
