    Hi. I am trying to build a custom sensor board to connect several sensors to Atmega328p microcontroller.

    If anyone can help me and look to the schematics, maybe point some errors, I would really appreciate it.

    It is ADXL345 connected to Atmega328p, also a slot for DS18B20 digital thermometer. I have several pads connected to control LEDs with PWM and one pad for interrupt input.

    Generally speaking, the interconnections look sensible, but depending on what Vcc is, you may have a logic level mismatch between the Atmega328p and the ADXL345. Also, I would add a 0.1uF bypass close to the Vcc pin on the Atmega328p. Finally, don't you want to have a 3x2 ICSP header in order to program your MC?
