This sensor has a lot of improvements that make it better for nearly any project.\u003c\/p\u003e\u003cp\u003eThe biggest improvement over plain photocells is a true log-lin relationship with light levels.

Sometimes you can tweak a resistor to make them better in dark or bright light but its hard to get good performance at both ends. This sensor is logarithmic over a large dynamic range of 3 to 55,000 Lux, so it has a lot of sensitivity at low light levels but is also nearly impossible to \u0026quot;max out\u0026quot; so you can use it indoors or outdoors without changing code or calibration.

It uses a UV photodiode, which can detect the 240-370nm range of light (which covers UVB and most of UVA spectrum). The signal level from the photodiode is very small, in the nano-ampere level, so we tossed on an opamp to amplify the signal to a more manageable volt-level.\u003c\/p\u003e\u003cp\u003eThis sensor is much simpler than our Si1145 breakout, it only does one thing and gives an analog voltage output instead of requiring a complicated I2C setup procedure. This makes it better for simple projects. It also has a \u0026#39;true\u0026#39; UV sensor instead of a calibrated light-sensor. To use, power the sensor and op-amp by connecting V+ to 2.7-5.5VDC and GND to power ground. Then read the analog signal from the OUT pin. The output voltage is: Vo = 4.3 * Diode-Current-in-uA. So if the photocurrent is 1uA (9 mW\/cm^2), the output voltage is 4.3V. You can also convert the voltage to UV Index by dividing the output voltage by 0.1V. So if the output voltage is 0.5V, the UV Index is about 5.\u003c\/p\u003e\u003cp\u003ePlease note, our UV LEDs are 400nm, outside the range of this sensor, so if you\u0026#39;re trying to test this sensor, don\u0026#39;t use them!

There\u0026#39;s an EEPROM so if you write the output voltage, you can \u0026#39;store it\u0026#39; so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/mcp4725-12-bit-dac-tutorial\"\u003eWe have an easy-to-use Arduino library and tutorial with a triangle-wave and sine-wave output example that can be used with any \u0026#39;duino or ported to any microcontroller with I2C host.\u003c\/a\u003e Wiring it up is easy - connect VDD to your microcontroller power pin (3-5V), GND to ground, SDA to I2C Data (on the Arduino Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2), SCL to I2C Clock(on the Arduino Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3) and listen on VOUT.\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43648740163798,"sku":"32-C5PJ-K4MT","price":9.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/2250\/3638\/products\/935-03.jpg?v=1664810447"}],"url":"https:\/\/paradisetronic.com\/en\/collections\/sensoren.oembed?page=13","provider":"Paradisetronic.com","version":"1.0","type":"link"}
