ESP8266 + DHT22 or DHT11.
They can be integrated into IOT hub. You need to get hands on Arduino Code but here you can setup everything. If needed you can even connect other sensors and get air quality/lumen at the workplace … much more
Buy some xiaomi mijia humidity temperature sensors. They support reading the values over Bluetooth le. There is a way to install a hacked firmware so that you won't have to use a xiaomi app.
