VMA328 USER MANUAL 1. Introduction To all residents of the European Union Important environmental information about this product This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm the environment. Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialized company for recycling. This device should be returned to your distributor or to a local recycling service. Respect the local environmental rules.
VMA328 5. Overview VMA328 Extend your light-sensing spectrum with this analogue UV sensor module. It uses a UV photodiode, which can detect the 240-370 nm 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. operating voltage: 3.3 V to 5 V output voltage: 0 V to 1 V (0-10 UV index) response time: 0.

Example 2 // CODE BEGIN void setup() { Serial.begin(9600); } void loop() { float sensorVoltage; float sensorValue; sensorValue = analogRead(A0); sensorVoltage = sensorValue/1024*3.3; // Change 3.3 to 5 if the power supply of the VMA328 is 5V. Serial.print("sensor reading = "); Serial.print(sensorValue); Serial.println(""); Serial.print("sensor voltage = "); Serial.print(sensorVoltage); Serial.println(" V"); delay(1000); } // CODE END 9.
