Temp/humidity card and sensor

[richard.mayo]

Am I right in thinking that the temp/humidity sensor and expansion card is to measure the air and not water... I.e don't put the probe in the water.....

Is this designed for aquariums or reptiles???

Thanks

You are right, it´s for air only. You can use it for terrarium, paludarium or your living room (as I do ;-)
