SENSOR TYPE

 HUMIDITY SENSOR (EMD-2000)

TEMPERATURE SENSOR (DS18B20)

First this the first sensor type that i want to use, but there is a problem to match with the program. After that, I ask my friend and electronic lecturer what is the easy to calibrate and match with my program and I choose HSM-2OG like picture below;

lucky the price is not to expensive according to the budget. Most of the expensive electronic component is using sensor and that the main thing we have to care and take serious.
