The sensor im using is called CHTA20 ive tried reading the instruction manual but its all in chinese i can read bit of it so i know the translations arent accurate
As for the loose connection issue i can just tape it down issue is if the sensor just breaks (and it has before) then i have to go and test one by one and the arduio is in a inconvenient place to access (cannot be moved anywhere else unfortunately so id rather not have to go and mess with that replacing the sensors(cutting the wires and attaching a new one) is actually far faster and simpler in this situation
Connections wise its the same as Arduino UNO connection with a TCA9548A along with CHTA20 Sensors
