Which components do we need?

Good morning everyone, me and my friend have been chosen, to do an Arduino project with a thermometer, this thermometer will send data about humidity, temperature and pressure to the application blynk via wifi. We need it to just know, which components we need to order and we dont want to buy something that we dont need. We are really new in this, and we will appreciate any suggestions, thank you for your time.

Yet we have some suggestions but we dont know if it will work or what else do we need.

IIC I2C Senzor Tlaku a Teploty BMP280 3,3V | dratek.cz - sensor
ESP8266 - WI-Fi microchip

The BME280 and a NodeMCU (ESP8266) sounds like a good combination to do what you state.
