This app will work if your phone has internal light sensor.
-----------------------------------------------
This App allows you to measure the light luminosity that goes from 0 to 1000 lux. You can use this app only for measuring the light luminosity or you can use it to turn your Android phone to IoT device. You can achieve this by filling in all the information here and turning on the switch. The first two sections from above you need to log in to the your e-mail, from which e-mails will be sent, and the third section for the e-mail account on which you will receive light luminocity informations, so the first and the third part may be the same. After that, you need only to specify the scope, from one number to another, that will make it your 'Defined area'. This app will use your 'Defined area' to send e-mail with current lux information to 'receiver's mail' every time when measured light luminocity is changed and if measured light luminocity is in your 'Defined area'. This app allows you to receive light luminosity informations, wherever you are, just from android device connected to wifi. If you want to send E-mail all fields need to be filled and with correct informations!

The best of all is that app is fully free!
