 # DoIt_ESP32_Devkit_V1_LightSensorData
 Repository to receive light sensor data.
+
+# Device
+The device used is a DoIt ESP32 Devkit V1 development board.
+
+# Measurements
+Measurements are done with a 10 Lux resolution light resistor.
+It is connected to GPIO34 (ADC1_ch6) since ADC2 doesn't work when using WiFi module.
