As arduino enthusiast, I buy a lot of sensors and arduino compatible boards to test. But I am very lazy so in the most of time, I just test the sensor and keep them stored. This is the result. The sensor sends temperature, air pressure and altitude to the site every 30 minutes. A friend of mine coded the site and the raspberry pi version. The humidity sensor is a Keyes dht11 and the air pressure sensor is a generic GY-65. Main board is a wemos d1 mini.
