Your project is neat. Some value able info for the people looking for the data collecting sites. For the Voltage reading with the help of voltage divider is the way to go. Try to use 1% of resistance for voltage divider. For power switch for BMP280, I would suggest to use a tiny MOSFET or bipolar transistor. The base or gate of the transistor could be controlled by the ESP32 io pin.

Hello Bodmer,Thank you for your quick reply. I tried it and it worked.I feel I am dumbo. It was a simple error message. I just have to declare the function in the startup of sketch. It is C thingi. I added this line at the start of the sketch after library includes. static uint8_t conv2d(const char* );ThanksRauf

Hello,Great library, and great help. I tried all examples given successfuly. However, when I tried digital clock examples, and got some errors during compiling on Arduino 1.6.6.I am not good at C, so far working with assembly on 8051 and variants. I recently started experimenting with Arduino and am surprized how easy it to get things done in Arduino if I compare them with struggle I use to have with 8051.I would appreciate your help in resolving this issue.
